The correct answer is B. 400 units.

Average total cost (ATC) is total cost (TC) divided by output (Q). In this case, ATC = 3 = TC/Q. We know that fixed costs (FC) are 400, so variable costs (VC) are TC - FC = 3Q - 400. We also know that AVC = VC/Q = 2.50. Substituting this into the equation for TC, we get 3Q - 400 = 2.50Q. Solving for Q, we get Q = 400 units.

Option A is incorrect because it is the average variable cost, not the average total cost. Option C is incorrect because it is twice the average total cost, which would mean that the firm is not covering its fixed costs. Option D is incorrect because it is four times the average total cost, which would mean that the firm is making a very large profit.

The correct answer is Chennai Super Kings.

Chennai Super Kings won the Indian Premier League (IPL) final for two consecutive years in 2010 and 2011. They defeated Mumbai Indians in the 2010 final by 22 runs, and they defeated Royal Challengers Bangalore in the 2011 final by six wickets.

The correct answer is: A. Stock concept.

A stock is a quantity of something that is available at a particular time. In economics, a stock is a measure of the amount of a good or service that is available at a given time. The supply of a commodity is the total amount of that commodity that is available for purchase at a given price.

A flow is a measure of the rate at which something changes over time. In economics, a flow is a measure of the amount of a good or service that is produced or consumed over a period of time. The supply of a commodity is not a flow because it does not measure the rate at which the commodity is produced or consumed. It measures the total amount of the commodity that is available for purchase at a given time.

The other options are incorrect because they do not accurately describe the supply of a commodity. Option B, "Flow concept," is incorrect because the supply of a commodity is not a flow. Option C, "Both stock and flow concept," is incorrect because the supply of a commodity is not both a stock and a flow. Option D, "None of the above," is incorrect because the supply of a commodity is a stock concept.

The occipital lobe is located at the back of the brain. It is involved in processing visual information.

The correct answer is (d), Delhi.

The South-West Monsoon is a seasonal wind pattern that brings heavy rains to India and other parts of South Asia. The monsoon season typically runs from June to September, and the amount of rainfall varies from place to place.

Kolkata, Mangalore, and Chennai are all located on the coast of India, and they receive a significant amount of rainfall during the monsoon season. Delhi, on the other hand, is located in the northern part of India, and it receives much less rainfall during the monsoon season.

In fact, Delhi is one of the driest cities in India. The average annual rainfall in Delhi is only about 700 mm, while the average annual rainfall in Kolkata is about 1,500 mm, the average annual rainfall in Mangalore is about 3,000 mm, and the average annual rainfall in Chennai is about 1,200 mm.

The reason why Delhi receives less rainfall than other parts of India is because it is located in a rain shadow. A rain shadow is an area that receives less rainfall than the surrounding areas because of the presence of mountains. In the case of Delhi, the Himalayas block the moisture-laden winds from the Bay of Bengal, which results in less rainfall in Delhi.

Menhdi was a 16th-century Indian artist who was born in Lucknow. He is considered to be one of the greatest henna artists of all time. He is credited with popularizing the use of henna in India.

The correct answer is Newton's first law of motion.

Newton's first law of motion states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This is also known as the law of inertia.

Newton's second law of motion states that the acceleration of an object is directly proportional to the net force acting on the object, and inversely proportional to the mass of the object. This is also known as the law of acceleration.

Newton's third law of motion states that for every action, there is an equal and opposite reaction. This is also known as the law of action and reaction.

There is no such thing as Newton's fourth law of motion.

The correct answer is D) All of the above.

The West Bengal government has taken several measures to reduce its fiscal deficit, such as increasing tax revenue, rationalizing expenditure, and promoting private investment.

Increasing tax revenue is one of the most important ways to reduce a fiscal deficit. By increasing taxes, the government can collect more money to spend on essential services and infrastructure. However, increasing taxes can also be unpopular, so it is important to do so in a way that does not harm the economy.

Rationalizing expenditure is another important way to reduce a fiscal deficit. This means cutting back on unnecessary spending and making sure that all spending is aligned with the government's priorities. Rationalizing expenditure can be difficult, but it is essential to ensure that the government is spending its money wisely.

Promoting private investment is another way to reduce a fiscal deficit. By creating a more attractive environment for businesses, the government can encourage them to invest in the state. This can lead to job creation and economic growth, which can help to reduce the deficit.

The West Bengal government has taken all of these measures in an effort to reduce its fiscal deficit. While it is too early to say whether these measures will be successful, they are a step in the right direction.

The correct answer is: B. to my address

The preposition "to" is used to indicate the destination of something. In this case, the letter is being sent to the address of the person who is being spoken to.

The preposition "on" is used to indicate a location on a surface. In this case, the letter is not being sent to a location on the address, but rather to the address itself.

The preposition "in" is used to indicate a location inside something. In this case, the letter is not being sent inside the address, but rather to the address itself.

The preposition "No improvement" is incorrect because the sentence is already grammatically correct.

WBSTC was established in 1989 and is responsible for operating bus service in the state.

The correct answer is D. no article.

The word "tall" is an adjective that describes the tree. Adjectives do not usually take articles.

The word "tree" is a common noun, which means it refers to a general class of things. Common nouns do not usually take articles unless they are specific or unique.

In this case, the tree is not specific or unique. It is just one of many tall trees. Therefore, we do not need to use an article.

The other options are incorrect because they are all articles. Articles are used to specify or identify a particular thing. In this case, there is no need to specify or identify the tree, so we do not need to use an article.

The correct answer is: A. monolithic structure

Ashokan pillars are monolithic, meaning they are carved from a single piece of stone. This is a remarkable feat of engineering, and it is one of the most striking features of the pillars.

The pillars are a testament to the skill and artistry of the Indian craftsmen who made them, and they are an important part of Indian history and culture.

The other options are incorrect because:

• B. carving: While the carving on the Ashokan pillars is indeed impressive, it is not the most striking feature. The monolithic structure is more striking.
• C. polish: The Ashokan pillars are polished, but this is not the most striking feature. The monolithic structure is more striking.
• D. uniformity of workmanship: The Ashokan pillars are uniformly well-made, but this is not the most striking feature. The monolithic structure is more striking.

The correct answer is C. Spinal cord.

The spinal cord is a long, thin, tubular bundle of nervous tissue that extends from the brain down the back through the spinal canal. It is made up of millions of nerve fibers that carry messages between the brain and the rest of the body.

The spinal cord is responsible for controlling many of the body's automatic functions, such as breathing, heart rate, and digestion. It also plays a role in movement, sensation, and reflexes.

Reflexes are involuntary actions that occur in response to a stimulus. For example, when you touch a hot stove, your hand will jerk away automatically. This reflex is controlled by the spinal cord, without any input from the brain.

The spinal cord is also responsible for transmitting messages from the brain to the muscles. These messages control voluntary movements, such as walking, talking, and eating.

The spinal cord is a vital part of the nervous system. It is responsible for controlling many of the body's automatic functions, as well as movement, sensation, and reflexes.

The other options are incorrect because:

• The cerebrum is the largest part of the brain. It is responsible for higher-level functions such as thinking, planning, and decision-making.

The answer is D. PRTV.

In each of the other options, the letters are in alphabetical order. In option D, the letters are not in alphabetical order.

The correct answer is: Only assumption II is implicit.

The statement "You really get your money's worth when you buy from our shop" is an advertisement. Advertisements are designed to persuade people to buy a product or service. In order to be persuasive, an advertisement must make an implicit assumption about the audience. In this case, the implicit assumption is that people want full value for their money. This assumption is necessary because the advertisement is trying to convince people that they will get full value for their money if they buy from the shop.

The other assumption, that other shops price goods above their worth, is not necessary for the advertisement to be persuasive. The advertisement could be just as persuasive if it simply said that people will get full value for their money at the shop, without making any comparison to other shops. Therefore, only assumption II is implicit.

Here is a more detailed explanation of each option:

• Option A: Only assumption I is implicit. This is the correct answer. Assumption I is necessary for the advertisement to be persuasive, but assumption II is not.
• Option B: Only assumption II is implicit. This is not the correct answer. Assumption II is not necessary for the advertisement to be persuasive.
• Option C: Either I or II is implicit. This is not the correct answer. Only assumption II is implicit.
• Option D: Neither I nor II is implicit. This is not the correct answer. Assumption II is implicit.
• Option E: Both I and II are implicit. This is not the correct answer. Only assumption II is implicit.

The correct answer is: A) Inland fish production.

West Bengal is the second largest producer of inland fish in India, after Andhra Pradesh. The state has a long coastline and a large number of rivers, lakes, and ponds. This makes it ideal for fish farming and fishing. The state government has also been promoting inland fish production in recent years, by providing subsidies and other incentives to farmers. As a result, the production of inland fish in West Bengal has increased significantly in recent years.

Option B is incorrect because West Bengal is not a desert state.

Option C is incorrect because West Bengal is not a deep-sea fishing state.

Option D is incorrect because West Bengal is not a mountain stream fishing state.

The correct answer is D. No improvement.

The sentence "It is time the six year old is learning how to read and write" is in the present progressive tense. This tense is used to talk about actions that are happening now or that are happening around the time of speaking. In this case, the speaker is saying that it is time for the six year old to start learning how to read and write. The present progressive tense is the most natural tense to use in this situation.

The other options are all in the past tense. The past tense is used to talk about actions that happened in the past. In this case, the speaker would be saying that the six year old has already learned how to read and write. This is not what the speaker is trying to say. The speaker is trying to say that it is time for the six year old to start learning how to read and write.

Therefore, the correct answer is D. No improvement.

The biosphere is the part of Earth where life exists. It includes the land, water, and air, as well as the organisms that live in these areas. The biosphere is a thin layer that surrounds the Earth, and it is constantly changing.

The thickness of the biosphere varies depending on the definition used. Some scientists define the biosphere as the part of Earth where life can exist, while others define it as the part of Earth where life does exist. The thickness of the biosphere is also affected by the presence of water. Water is essential for life, and it is found in the atmosphere, on the land, and in the oceans. The thickness of the biosphere is therefore greater in areas where there is more water.

The biosphere is a dynamic system that is constantly changing. The Earth's climate is changing, and this is affecting the biosphere. The biosphere is also affected by human activities, such as pollution and deforestation. These activities are causing the biosphere to shrink, and they are also causing the biosphere to become more polluted.

The biosphere is a vital part of Earth, and it is important to protect it. We need to reduce pollution and deforestation, and we need to find ways to adapt to climate change. We also need to learn more about the biosphere, so that we can better understand how it works and how we can protect it.

The other options are incorrect because they do not accurately reflect the thickness of the biosphere. Option A is too high, and option B is too low. Option D is also too high, and it is not supported by scientific evidence.

The correct answer is: A. New Delhi

The other options are incorrect because:

• Ahmedabad is a city in Gujarat, India.
• Kolkata is a city in West Bengal, India.
• Mumbai is a city in Maharashtra, India.

The correct answer is: D. Neither I nor II is strong

Argument I is not strong because it is based on the assumption that all religions develop fanaticism in people. This is not necessarily true. There are many religions that promote peace and tolerance.

Argument II is not strong because it is based on the assumption that religion is the only thing that binds people together. This is also not necessarily true. There are many other things that can bind people together, such as shared interests, common values, and a sense of community.

In conclusion, neither argument I nor II is strong enough to support the conclusion that religion should be banned.

The correct answer is A. Lamarck.

Jean-Baptiste Lamarck was a French naturalist who proposed the theory of use and disuse to explain evolution. He believed that organisms could pass on acquired characteristics to their offspring. For example, he thought that giraffes developed long necks because they stretched their necks to reach leaves on tall trees.

Charles Darwin was a British naturalist who proposed the theory of natural selection to explain evolution. He believed that organisms that are better adapted to their environment are more likely to survive and reproduce. This leads to the gradual evolution of species.

Hugo de Vries was a Dutch botanist who proposed the theory of mutation to explain evolution. He believed that evolution occurs in large jumps, or mutations, rather than gradually.

Alfred Russel Wallace was a British naturalist who independently developed the theory of natural selection. He was a contemporary of Darwin and they corresponded extensively.

The theory of use and disuse is no longer accepted by the scientific community. However, it was an important step in the development of our understanding of evolution.

The correct answer is D. Anatomy.

Anatomy is the study of the human body, its structures, and how they function. It is a branch of biology that is closely related to physiology, which is the study of how the body's systems work.

Anthropology is the study of human beings, their origins, and their development. It is a social science that is closely related to archaeology, which is the study of human history through the excavation of artifacts.

Neurology is the study of the nervous system, which is the part of the body that controls movement, sensation, and thought. It is a medical specialty that is closely related to psychiatry, which is the study of mental disorders.

Hygiene is the practice of keeping oneself and one's environment clean and healthy. It is a branch of medicine that is closely related to sanitation, which is the practice of preventing the spread of disease.

The correct answer is A. CO.

The two-letter country code for Colombia is CO. It is used to identify Colombia in international communications. It is also used in the top-level domain (TLD) for Colombia, which is .co.

The other options are incorrect. B. CM is the two-letter country code for Cameroon. C. CL is the two-letter country code for Chile. D. CB is the two-letter country code for the Central African Republic.

The correct answer is: A. Rate of substitution.

An isoquant is a curve that shows all the combinations of inputs that produce the same level of output. The rate of substitution is the amount of one input that must be given up to obtain an additional unit of another input while keeping output constant. The rate of substitution is not constant along an isoquant, but it is diminishing. This means that as you use more of one input, you have to give up less of the other input to keep output constant.

The rate of substitution is important because it tells us how much one input can be substituted for another without changing output. This information is useful for firms that are trying to find the least-cost combination of inputs to produce a given level of output.

The other options are incorrect because they do not affect the relationship of the isoquant curve line. The cost rate is the amount of money that a firm spends on inputs. The rate of production is the amount of output that a firm produces. Neither of these factors affect the relationship between the inputs and outputs that are represented by an isoquant.

The correct answer is (d), India.

The Asian-Pacific Trade Agreement (APTA) is a free trade agreement between 16 countries in the Asia-Pacific region. It was established in 1975 and is the oldest regional trade agreement in the Asia-Pacific region. The agreement aims to promote trade and investment between the member countries by reducing tariffs and other trade barriers.

The member countries of APTA are:

• Bangladesh
• Bhutan
• Brunei
• Cambodia
• China
• India
• Indonesia
• Japan
• Laos
• Malaysia
• Myanmar
• Nepal
• Pakistan
• Singapore
• Sri Lanka
• Thailand

India is not a member of APTA because it has not ratified the agreement. India has been a signatory to the agreement since 1997, but it has not yet ratified the agreement. The main reason for India's non-ratification of the agreement is that India wants to protect its domestic industries from competition from other countries in the region.

India is a large and growing economy, and it has a large domestic market. Indian companies are concerned that if they are exposed to competition from other countries in the region, they will not be able to compete and will lose market share. This is why India has not yet ratified the APTA agreement.

However, India is in the process of negotiating a free trade agreement with China. If this agreement is successful, it could lead to India ratifying the APTA agreement. This is because India would be able to protect its domestic industries from competition from China by negotiating special provisions in the free trade agreement.

Overall, India is not a member of APTA because it has not ratified the agreement. The main reason for India's non-ratification of the agreement is that India wants to protect its domestic industries from competition from other countries in the region. However, India is in the process of negotiating a free trade agreement with China, and if this agreement is successful, it could lead to India ratifying the APTA agreement.

The correct answer is (b), 31st March, 1973.

Kumaun Mandal Vikas Nigam and Garhwal Mandal Vikas Nigam were established on 31st March, 1973 by the Uttar Pradesh government to promote the economic development of the Kumaon and Garhwal regions of Uttarakhand. The two corporations were merged in 2000 to form the Uttarakhand State Industrial Development Corporation.

The correct answer is: C. Same as the weight of the man.

When a man stands in a lift which accelerates upwards, the man experiences two forces: the force of gravity pulling him down, and the reaction force of the floor of the lift pushing him up. The reaction force of the floor of the lift is equal in magnitude but opposite in direction to the force of gravity, so the net force on the man is zero. This means that the man does not accelerate, and his weight remains the same.

Option A is incorrect because the reaction force of the floor of the lift cannot be greater than the force of gravity. The force of gravity is a fundamental force of nature, and it is impossible for any other force to be greater than it.

Option B is incorrect because the reaction force of the floor of the lift cannot be less than the force of gravity. The man is standing on the floor of the lift, and the floor of the lift is supporting his weight. If the reaction force of the floor of the lift were less than the force of gravity, the man would fall through the floor.

Option D is incorrect because the reaction force of the floor of the lift cannot be zero. The man is standing on the floor of the lift, and the floor of the lift is supporting his weight. If the reaction force of the floor of the lift were zero, the man would float in the air.

The answer is C. Rain.

Fog, cloud, and mist are all forms of water vapor in the atmosphere. Fog is a cloud that forms at ground level, while clouds form higher up in the atmosphere. Mist is a thin fog that is not as dense as fog. Rain is water that falls from clouds to the ground.

Rain is the only option that is not a form of water vapor in the atmosphere. Rain is water that has condensed from clouds and fallen to the ground.

The correct answer is A. Spleen.

The spleen is an organ in the human body that is located in the upper left abdomen. It is part of the lymphatic system, which helps to fight infection. The spleen also helps to remove old red blood cells from the blood.

The pituitary gland is a small, pea-sized gland located at the base of the brain. It is often called the "master gland" because it produces hormones that control many other glands in the body.

The thyroid gland is a butterfly-shaped gland located in the neck. It produces hormones that regulate metabolism, growth, and development.

The adrenal glands are two small glands located on top of the kidneys. They produce hormones that help to regulate the body's response to stress, as well as hormones that regulate blood sugar levels.

The spleen is not an endocrine gland because it does not produce hormones.

The correct answer is C.

The correct answer is B. Photosynthesis.

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar. This process is essential for life on Earth, as it provides the oxygen that we breathe and the food that we eat.

Transpiration is the process by which plants lose water vapor through their leaves. This process helps to cool the plant and to transport nutrients and minerals from the roots to the leaves.

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. This process is important in many biological processes, including the transport of nutrients and gases across cell membranes.

Osmosis is the movement of water across a semipermeable membrane from an area of high water concentration to an area of low water concentration. This process is important in the transport of water and nutrients into and out of cells.

The correct answer is: A perfectly competitive firm should reduce output or shut down in the short run if market price is equal to marginal cost, and the price is less than average variable cost.

A perfectly competitive firm is a price taker, which means that it cannot influence the market price of its product. The firm's marginal cost curve intersects its average variable cost curve at the minimum point of the average variable cost curve. If the market price is equal to or greater than the average variable cost, the firm will produce at the point where marginal cost equals price. However, if the market price is less than the average variable cost, the firm will not produce any output, because it will lose money on every unit produced.

Here is a diagram that illustrates the concept:

[Diagram of a perfectly competitive firm's cost curves]

The firm's marginal cost curve is MC, its average total cost curve is ATC, and its average variable cost curve is AVC. The market price is P. If the market price is equal to or greater than the average variable cost, the firm will produce at the point where marginal cost equals price. However, if the market price is less than the average variable cost, the firm will not produce any output, because it will lose money on every unit produced.

In conclusion, a perfectly competitive firm should reduce output or shut down in the short run if market price is equal to marginal cost, and the price is less than average variable cost.

The correct answer is A. Unrestrained.

Incontinent means unable to control one's bowel or bladder movements. It can also mean lacking in self-control or restraint.

Unrestrained means not controlled or limited. It can also mean free from restraint or control.

Restless means unable to keep still or quiet. It can also mean feeling or showing a lack of peace or quiet.

Inconstant means not staying the same for long. It can also mean changing frequently or suddenly.

Uncertain means not sure or definite. It can also mean not having or showing confidence.

In this case, the word "incontinent" is most closely related to the word "unrestrained." Both words mean not being able to control oneself. In the case of incontinent, this means not being able to control one's bowel or bladder movements. In the case of unrestrained, this means not being able to control one's behavior.

The other words are not as closely related to "incontinent." Restless means unable to keep still or quiet, which is not the same as not being able to control oneself. Inconstant means not staying the same for long, which is not the same as not being able to control oneself. Uncertain means not sure or definite, which is not the same as not being able to control oneself.

The correct answer is (a) 2015-16.

Samagra Shiksha Abhiyan (SSA) is a flagship programme of the Government of India for the universalization of elementary education (UEE) in the country. It was launched in 2015-16 as an umbrella programme integrating the erstwhile Sarva Shiksha Abhiyan (SSA), Rashtriya Madhyamik Shiksha Abhiyan (RMSA), and the Teacher Education Programme (TEP).

The SSA aims to provide quality elementary education to all children in the age group of 6-14 years by 2020. It focuses on improving access, equity, quality, and efficiency in elementary education. The SSA is implemented through the state governments and union territories.

The dropout rate has also declined from 10.1% in 2015-16 to 6.3% in 2019-20. The SSA has also made significant progress in improving the quality of education. The learning outcomes of students have improved, and the infrastructure in schools has been upgraded.

The SSA is a major step towards achieving the goal of universal education in India. It has made significant progress in improving access, equity, quality, and efficiency in elementary education. The SSA is expected to continue to play a key role in the development of elementary education in India in the years to come.

The other options are incorrect because they are not the years in which the SSA was started.

The correct answer is D. All of the above.

Opportunity cost is the cost of an alternative that must be forgone in order to pursue a certain action. For example, if you choose to go to work, you are forgoing the opportunity to relax at home. Time reference is the idea that the value of something depends on when it is received. For example, $100 today is worth more than $100 in a year because you can invest the $100 today and earn interest on it. Equimarginal is the idea that you should allocate your resources in such a way that the marginal benefit of each resource is equal. For example, if you are trying to decide how much to spend on advertising, you should spend money on advertising until the marginal benefit of advertising is equal to the marginal cost of advertising.

Opportunity cost is a fundamental concept in economics. It is the cost of any activity that is given up in order to pursue another activity. Opportunity cost is often used to compare the costs and benefits of different choices. For example, if you are trying to decide whether to go to college or get a job, you need to consider the opportunity cost of each option. The opportunity cost of going to college is the income you could have earned if you had gotten a job instead. The opportunity cost of getting a job is the education you could have received if you had gone to college instead.

Time reference is another important concept in economics. It is the idea that the value of something depends on when it is received. For example, $100 today is worth more than $100 in a year because you can invest the $100 today and earn interest on it. This is because money has time value. The time value of money is the idea that money is worth more today than it will be in the future because you can earn interest on it.

Equimarginal is a concept in economics that states that you should allocate your resources in such a way that the marginal benefit of each resource is equal. For example, if you are trying to decide how much to spend on advertising, you should spend money on advertising until the marginal benefit of advertising is equal to the marginal cost of advertising. This is because you should not spend more money on advertising than you are getting in return.

The correct answer is (a) 1985.

The Act has been amended several times since its enactment. The most recent amendment was in 2015. The amendment has made several changes to the Act, including raising the age of juvenile from 18 to 21 years.

The Juvenile Justice Act, 1985 is an important piece of legislation that has helped to improve the lives of juveniles in India. The Act has provided for the care, protection, treatment, development and rehabilitation of juveniles. It has also helped to reduce the incidence of juvenile delinquency in India.

The other options are incorrect because they are not the years in which the Juvenile Justice Act was passed in India.

In addition, remittances can also help to reduce poverty, improve gender equality, and promote social cohesion.

The correct answer is B. WBC.

White blood cells (WBCs) are the cells in the blood that fight infection. They are also called leukocytes. There are many different types of WBCs, each with a different function. Some WBCs engulf and destroy bacteria, while others produce antibodies that attack bacteria or viruses.

When a foreign body enters the blood, the WBCs are the first to respond. They travel to the site of the infection and release chemicals that kill the bacteria or virus. They also help to remove dead cells and debris from the area.

RBCs, or red blood cells, are the cells in the blood that carry oxygen to the tissues. They are not involved in fighting infection.

Platelets are the cells in the blood that help to stop bleeding. They do this by forming a clot at the site of the injury.

Cytoplasm is the jelly-like substance inside cells. It is not involved in fighting infection.

In conclusion, the correct answer is B. WBC. WBCs are the cells in the blood that fight infection. They are the first to respond when a foreign body enters the blood.

The correct answer is D.

Economic liberalism started in India in the early 1990s, with the introduction of a series of economic reforms. These reforms included substantial changes in the licensing policy, removal of procedural hurdles for foreign direct investment, and significant reductions in the import tax rates.

The licensing policy was a system that required businesses to obtain a license from the government before they could start or expand operations. This system was very restrictive and made it difficult for businesses to operate. The reforms abolished the licensing policy, which made it easier for businesses to start and expand operations.

The reforms also removed procedural hurdles for foreign direct investment. This made it easier for foreign companies to invest in India. The reforms also significantly reduced the import tax rates. This made it cheaper for businesses to import goods and services.

The correct answer is (b).

CRR stands for Cash Reserve Ratio. It is the percentage of the total deposits that banks are required to keep with the Reserve Bank of India (RBI). When the RBI increases the CRR, banks have to keep more money with the RBI and less money available to lend to customers. This reduces the amount of money in circulation in the economy, which is known as liquidity.

A reduction in liquidity can have a number of effects on the economy. It can make it more difficult for businesses to get loans, which can lead to slower economic growth. It can also lead to higher interest rates, as banks will need to charge more to compensate for the fact that they have less money to lend.

However, a reduction in liquidity can also be used to control inflation. When there is too much money in circulation, prices tend to rise. By reducing liquidity, the RBI can help to bring down inflation.

In conclusion, an increase in CRR by the Reserve Bank of India results in a reduction in liquidity in the economy. This can have a number of effects on the economy, including slower economic growth, higher interest rates, and lower inflation.

Amplification is the process of increasing the amplitude of a signal. This can be done using a variety of electronic components, including transistors, vacuum tubes, and op-amps. Amplification is often used in audio and video systems to increase the volume of sound or the brightness of an image.

Modulation is the process of changing one signal (the carrier signal) in accordance with another signal (the modulating signal). This can be done by varying the amplitude, frequency, or phase of the carrier signal. Modulation is often used in telecommunications to transmit information over long distances.

Filtering is the process of removing unwanted components from a signal. This can be done using a variety of electronic components, including capacitors, inductors, and resistors. Filtering is often used in audio and video systems to remove noise and interference.

In conclusion, diodes are generally used for rectification. This is because they allow current to flow in one direction only, which is necessary for converting AC to DC.

The correct answer is: A) Boycott of British goods.

The Swadeshi movement was a socio-political movement in India that originated in Bengal in 1905. It was a protest against the partition of Bengal and British rule in India. The movement advocated for the boycott of British goods, the promotion of Indian-made goods, and the use of the Bengali language. The movement was successful in achieving some of its goals, such as the reversal of the partition of Bengal. However, it was ultimately unsuccessful in overthrowing British rule in India.

Option B, promotion of Western education, is incorrect because the Swadeshi movement was a reaction against Western influence in India. The movement's leaders believed that India should develop its own culture and economy, independent of Western influence.

Option C, adoption of British culture, is incorrect for the same reason as option B. The Swadeshi movement was a reaction against Westernization. The movement's leaders believed that India should preserve its own culture and values.

Option D, support for British rule, is incorrect because the Swadeshi movement was a protest against British rule. The movement's leaders believed that India should be an independent country.

The correct answer is: A) Rural to urban migration.

Rural to urban migration is a major trend observed in West Bengal. This is due to a number of factors, including the following:

* The state's economy is growing rapidly, and there are more job opportunities in urban areas.
* Urban areas offer better infrastructure and amenities than rural areas.
* Many people are moving to urban areas in search of a better quality of life.

Rural to urban migration can have a number of positive and negative effects on the state. On the positive side, it can lead to economic growth and development. It can also lead to the spread of new ideas and technologies. However, rural to urban migration can also lead to overcrowding, pollution, and social problems.

The state government is taking a number of steps to address the challenges of rural to urban migration. These include the following:

* Investing in rural infrastructure and amenities.
* Creating more job opportunities in rural areas.
* Promoting education and awareness about the benefits of living in rural areas.

It is important to manage rural to urban migration in a way that benefits both the state and the migrants. The state government needs to ensure that there are adequate job opportunities and infrastructure in urban areas. It also needs to provide support to migrants who are struggling to adjust to life in urban areas.

The correct answer is A. Rises.

Income elasticity of demand is a measure of how responsive the demand for a good or service is to changes in consumer income. It is calculated as the percentage change in the quantity demanded divided by the percentage change in income.

A positive income elasticity of demand means that the demand for a good or service increases as income increases. This is because as people have more money, they are able to afford to buy more of the good or service.

A negative income elasticity of demand means that the demand for a good or service decreases as income increases. This is because as people have more money, they are able to afford to buy more of other goods and services, and so they buy less of the good or service in question.

An income elasticity of demand of zero means that the demand for a good or service does not change as income changes. This is because the good or service is considered to be a necessity, and so people will buy the same amount of it regardless of their income.

In conclusion, the correct answer is A. Rises.

The correct answer is (c) U.S.A.

The federal system of India was inspired by the Constitution of the United States of America. The Indian Constitution was adopted on 26 November 1949 and came into effect on 26 January 1950. It is the longest written constitution of any country in the world.

The Indian Constitution is based on the principle of federalism, which means that power is shared between the central government and the state governments. The central government has power over matters such as defense, foreign affairs, and currency. The state governments have power over matters such as education, health, and agriculture.

The Indian Constitution also provides for a system of checks and balances between the central government and the state governments. This means that no one branch of government can become too powerful.

The federal system of India has been successful in promoting unity and diversity in the country. It has also helped to protect the rights of the people.

The other options are incorrect because:

(a) Canada is a federal state, but its constitution was not the main inspiration for the Indian Constitution.
(b) The United Kingdom is a unitary state, which means that power is concentrated in the central government.
(c) Ireland is a unitary state.
(d) Ireland is a unitary state.

The answer is D. Cow : Shed.

A garage is a building or structure where vehicles are kept, a sty is a pen or enclosure for pigs, and a stable is a building or enclosure for horses. A shed is a small building or shelter, typically used for storage or as a workshop.

While a shed can be used to house a cow, it is not the most common or traditional type of housing for cows. Cows are typically housed in barns, which are larger and more well-suited to their needs. Sheds are more commonly used for housing smaller animals, such as chickens or rabbits.

Therefore, the odd word in the list is "shed".

The other three options, A. GE, B. MK, and C. WU, are all pairs of letters that are next to each other on the alphabet. QN is not a pair of letters that are next to each other on the alphabet.

The correct answer is A. Fundamental right.

A fundamental right is a right that is considered to be essential to a person's freedom and dignity. It is a right that is protected by the law and cannot be taken away by the government.

The right to property is a fundamental right in India. It is guaranteed by Article 300A of the Constitution. This article states that no person shall be deprived of his property except by due process of law.

The right to property is important because it allows people to own and control their own property. This includes land, houses, cars, and other assets. The right to property also allows people to earn a living and to provide for their families.

The right to property is not absolute. It can be limited by the government in certain circumstances. For example, the government can take away property for public purposes, such as building a road or a school. However, the government must pay compensation for any property that it takes away.

The right to property is a fundamental right that is important for the freedom and dignity of individuals. It is a right that is protected by the law and cannot be taken away by the government without due process of law.

The other options are incorrect because:

• A natural right is a right that is believed to be inherent in all people, regardless of their nationality, race, or religion.
• A legal right is a right that is created by law.
• A moral right is a right that is based on what is considered to be right and wrong.

The correct answer is D. No error.

The sentence "The warden forbade the student from leaving the hostel" is grammatically correct. The word "forbade" is a verb that means "to order someone not to do something." The word "student" is a noun that refers to a person who is enrolled in a school. The word "from" is a preposition that indicates that the student is not allowed to leave the hostel. The word "leaving" is a verb that means "to go away from a place." The word "hostel" is a noun that refers to a building where students live.

The sentence is grammatically correct because it follows the rules of English grammar. The word order is correct, and the verbs agree with the subjects. The sentence also makes sense, and it is clear what the writer is trying to say.

The answer is D. Minister.

A king, queen, bishop, and knight are all pieces in the game of chess. A minister is not a piece in chess.

A king is the most important piece in chess. It is the only piece that can move to any square on the board. The goal of the game is to checkmate the opponent's king, which means to put it in a position where it cannot move without being captured.

A queen is the second most important piece in chess. It can move any number of squares in any direction.

A bishop is a piece that can move diagonally any number of squares.

A knight is a piece that can move two squares horizontally and one square vertically, or one square horizontally and two squares vertically.

A minister is not a piece in chess. It is a person who is responsible for a particular area of government or religious affairs.

The correct answer is (c).

The percentage change in population in India from 1991 to 2001 was 21.3%, which is the lowest among the given options. The percentage change in population from 1971 to 1981 was 24.66%, from 1981 to 1991 was 23.85%, and from 2001 to 2011 was 17.64%.

The decline in the percentage change in population from 1991 to 2001 can be attributed to a number of factors, including:

• A decline in the fertility rate. The total fertility rate in India declined from 3.2 in 1991 to 2.6 in 2001. This means that women are having fewer children on average.
• An increase in the average age of marriage. The average age of marriage for women in India increased from 18.3 in 1991 to 20.9 in 2001. This means that women are having children later in life, which also contributes to a decline in the fertility rate.
• An increase in the use of contraception. The use of contraception in India increased from 46% in 1991 to 56% in 2001. This means that more couples are using contraception to prevent pregnancy, which also contributes to a decline in the fertility rate.

The decline in the percentage change in population is a positive development for India. It means that the country is becoming more developed and that people are having fewer children. This will put less strain on the country's resources and will help to improve the quality of life for all Indians.

The correct answer is: A) Royal Bengal Tiger.

The correct answer is: C. Phototactic.

Phototaxis is the movement of an organism in response to a light stimulus. It is a type of taxis, a general term for movement in response to a stimulus. Phototaxis can be positive, meaning that the organism moves towards the light, or negative, meaning that the organism moves away from the light.

In insects, phototaxis is often used to find food or mates. Some insects, such as moths, are attracted to light at night. This is because they use the moon to navigate, and they can become confused by artificial light sources. Other insects, such as fireflies, use light to attract mates.

Phototaxis can also be used to avoid predators. Some insects, such as grasshoppers, will jump away from light. This is because they are sensitive to ultraviolet light, which is emitted by many predators.

Phototaxis is a complex behavior that is controlled by a number of different genes. It is an important survival mechanism for many insects, and it plays a role in a variety of other behaviors, such as reproduction and migration.

A. Phototropism is the growth of a plant part in response to a light stimulus. It is a type of tropism, a general term for growth in response to a stimulus. Phototropism can be positive, meaning that the plant part grows towards the light, or negative, meaning that the plant part grows away from the light.

B. Hydrotropism is the growth of a plant part in response to a water stimulus. It is a type of tropism, a general term for growth in response to a stimulus. Hydrotropism can be positive, meaning that the plant part grows towards the water, or negative, meaning that the plant part grows away from the water.

D. Thermotaxis is the movement of an organism in response to a temperature stimulus. It is a type of taxis, a general term for movement in response to a stimulus. Thermotaxis can be positive, meaning that the organism moves towards the heat, or negative, meaning that the organism moves away from the heat.

The scheme provides financial assistance to girls from poor families to attend school, and also provides them with scholarships and other forms of support. The scheme has been successful in increasing the enrollment of girls in schools, and has also helped to improve their academic performance.

Option B is incorrect because the Utkarsh Bangla scheme is not focused on skill development and vocational training. However, there are other government schemes in West Bengal that focus on these areas.

Option C is incorrect because the Utkarsh Bangla scheme is not focused on providing healthcare to children. However, there are other government schemes in West Bengal that focus on these areas.

Option D is incorrect because the Utkarsh Bangla scheme is not focused on improving sanitation facilities in schools. However, there are other government schemes in West Bengal that focus on these areas.

The correct answer is C. 1997.

Hong Kong was transferred from British to Chinese rule on July 1, 1997, in accordance with the Sino-British Joint Declaration, which was signed on December 19, 1984. The Joint Declaration stipulated that Hong Kong would be governed under a "one country, two systems" principle for 50 years after the handover. This means that Hong Kong would retain its own economic, political, and social systems, separate from those of mainland China.

The handover of Hong Kong was a major event in Chinese history. It marked the end of British colonial rule in Hong Kong and the beginning of a new era of Chinese sovereignty over the territory. The handover was also a significant event in the history of Hong Kong. It marked the end of a period of rapid economic growth and development, and the beginning of a new era of uncertainty and change.

The handover of Hong Kong was a complex and controversial event. There were many different opinions about the future of Hong Kong, and the handover was met with both celebration and protest. However, the handover was ultimately a peaceful and orderly process, and Hong Kong has since become a prosperous and vibrant city.

The options A, B, and D are incorrect because they are not the years in which Hong Kong was transferred to China.

In 1942, Sisir Kumar Bhaduri established Srirangam which is now known as Biswarupa Theatre.

The correct answer is A. Fungus.

Yeast is a single-celled fungus that is used in baking to make bread rise. It is a living organism that converts sugar into carbon dioxide and alcohol. The carbon dioxide bubbles cause the dough to rise, and the alcohol evaporates during baking.

Bacteria are also single-celled organisms, but they are not fungi. Bacteria are much smaller than yeast cells, and they do not have a nucleus. Bacteria can cause diseases, but they can also be used to make yogurt, cheese, and other fermented foods.

Seeds are the reproductive units of plants. They contain an embryo plant and a food supply that the embryo uses to grow. Seeds are usually enclosed in a protective coat.

Plants are multicellular organisms that are photosynthetic. They make their own food using sunlight, water, and carbon dioxide. Plants have roots, stems, leaves, and flowers.

In conclusion, yeast is a fungus that is used in baking to make bread rise. It is a living organism that converts sugar into carbon dioxide and alcohol. The carbon dioxide bubbles cause the dough to rise, and the alcohol evaporates during baking.

The correct answer is D. All of the above are major challenges to fiscal management in West Bengal.

A high revenue deficit means that the state government is spending more money than it is taking in through taxes and other revenue sources. This can lead to a number of problems, including a decline in the state's credit rating, which makes it more difficult to borrow money. It can also lead to inflation, as the government is forced to print more money to cover its expenses.

Growing public debt is another major challenge to fiscal management in West Bengal. The state's debt has been increasing steadily in recent years, and it is now one of the highest in the country. This means that the state government is paying a lot of interest on its debt, which takes away money that could be used for other purposes, such as education and healthcare.

Increasing expenditure on subsidies is also a major challenge to fiscal management in West Bengal. The state government spends a lot of money on subsidies, such as food subsidies and fuel subsidies. These subsidies can be helpful to low-income households, but they can also put a strain on the state's budget.

All of these challenges make it difficult for the state government of West Bengal to manage its finances effectively. This can have a number of negative consequences, such as a decline in the quality of public services, an increase in taxes, and a decrease in investment.

The correct answer is B. Work and Power.

Work is the product of force and distance, while power is the rate at which work is done. Both work and power have the dimensions of force times distance, or $ML^2T^{-2}$.

Force is the product of mass and acceleration, while momentum is the product of mass and velocity. Both force and momentum have the dimensions of mass times acceleration, or $MLT^{-2}$.

Energy is the ability to do work, while momentum is the product of mass and velocity. Both energy and momentum have the dimensions of mass times length squared times time squared, or $ML^2T^{-2}$.

Therefore, the only pair of physical quantities that have the same dimensions is work and power.

The correct answer is (d). Guanine is a purine base.

Purine bases are nitrogenous bases that are found in DNA and RNA. They are double-ringed molecules that are made up of a pyrimidine ring and an imidazole ring. Purines are essential for the structure and function of DNA and RNA. They are also involved in the regulation of gene expression.

Thymine, cytosine, and uracil are pyrimidine bases. They are single-ringed molecules that are made up of a pyrimidine ring and a pyrimidine ring. Pyrimidine bases are also found in DNA and RNA. They are involved in the formation of base pairs.

Thymine is complementary to adenine. Cytosine is complementary to guanine. Uracil is complementary to adenine in RNA.

Purine bases are larger than pyrimidine bases. They are also more hydrophobic than pyrimidine bases. This difference in size and hydrophobicity is important for the structure and function of DNA and RNA.

Purine bases are essential for life. They are involved in the storage and transmission of genetic information. They are also involved in the regulation of gene expression.

The correct answer is (a) Haryana.

Haryana recorded the lowest sex-ratio of 879 females per 1000 males in the 2011 census. This means that for every 1000 males in Haryana, there were only 879 females. This is significantly lower than the national average of 940 females per 1000 males.

There are a number of factors that contribute to the low sex-ratio in Haryana. One factor is the practice of female foeticide, which is the selective abortion of female fetuses. This is often done due to a preference for sons, who are seen as being more valuable than daughters. Another factor is the high rate of female infant mortality, which is the death of a girl child before her first birthday. This is often due to neglect or malnutrition.

The low sex-ratio in Haryana has a number of negative consequences. It can lead to a shortage of women in the workforce, which can impact the economy. It can also lead to social problems, such as an increase in crime and violence.

The government of Haryana has taken a number of measures to address the issue of the low sex-ratio. These measures include awareness campaigns, stricter laws against female foeticide, and programs to improve the health and well-being of girls and women.

Despite these measures, the problem of the low sex-ratio in Haryana remains a serious one. It is important to continue to raise awareness of the issue and to take steps to address it.

The correct answer is: B) Indo-Saracenic architecture.

The correct answer is (a) 1580.

Din-i-Ilahi was a new religion created by Mughal emperor Akbar in 1580. It was a syncretic religion that combined elements of Islam, Hinduism, Christianity, Zoroastrianism, and Jainism. Akbar believed that Din-i-Ilahi would unite his subjects and promote religious tolerance.

Option (b) is incorrect because Din-i-Ilahi was created in 1580, not 1581.

Option (c) is incorrect because Din-i-Ilahi was created in 1580, not 1582.

Option (d) is incorrect because Din-i-Ilahi was created in 1580, not 1583.

The correct answer is B. $frac{1}{{{text{y}} - {text{x}}}}$.

A probability density function (PDF) is a function that describes the probability of a continuous random variable taking on a certain value. The PDF of a uniform distribution is a constant function over the interval of interest, and zero elsewhere. In this case, the interval of interest is $[x, y]$, so the PDF is $frac{1}{{{text{y}} - {text{x}}}}$.

Option A, $y - x$, is not a probability density function because it is not non-negative and does not integrate to 1. Option C, $x - y$, is also not a probability density function because it is not non-negative. Option D, $frac{1}{{{text{x}} - {text{y}}}}$, is not a probability density function because it is not defined for $x > y$.

The correct answer is: C. Mean of f(x) and g(x) are different; Variance of f(x) and g(x) are same.

The mean of a probability density function is given by:

$$mu = int_{-infty}^{infty} x f(x) dx$$

The variance of a probability density function is given by:

$$sigma^2 = int_{-infty}^{infty} (x - mu)^2 f(x) dx$$

For $f(x)$ and $g(x)$ as given in the question, we have:

$$mu_f = int_{-a}^0 x frac{x}{a} + 1 dx = frac{a^2}{4} + 0 = frac{a^2}{4}$$

$$mu_g = int_{-a}^0 x frac{-x}{a} + 1 dx = -frac{a^2}{4} + 0 = -frac{a^2}{4}$$

Therefore, $mu_f neq mu_g$.

The variance of $f(x)$ is given by:

$$sigma^2_f = int_{-a}^0 (x - mu_f)^2 frac{x}{a} + 1 dx = frac{a^4}{16} + 0 = frac{a^4}{16}$$

The variance of $g(x)$ is given by:

$$sigma^2_g = int_{-a}^0 (x - mu_g)^2 frac{-x}{a} + 1 dx = frac{a^4}{16} + 0 = frac{a^4}{16}$$

Therefore, $sigma^2_f = sigma^2_g$.

Therefore, the mean of $f(x)$ and $g(x)$ are different, but the variance of $f(x)$ and $g(x)$ are the same.

The correct answer is: A. ionosphere

The ionosphere is a region of Earth's atmosphere that is ionized by solar radiation. It is located above the stratosphere and extends from about 50 to 1,000 kilometers (31 to 620 miles) above the Earth's surface. The ionosphere is important for radio communications because it reflects radio waves back to Earth.

The temperature of the ionosphere increases with altitude. This is because the solar radiation that ionizes the atmosphere also heats it. The highest temperatures in the ionosphere are found in the thermosphere, which is the outermost layer of the ionosphere. The thermosphere extends from about 80 to 600 kilometers (50 to 370 miles) above the Earth's surface.

The other options are incorrect because they are not regions of Earth's atmosphere where the temperature increases rapidly. The troposphere is the lowest layer of Earth's atmosphere. It extends from the Earth's surface to about 12 kilometers (7.5 miles) above sea level. The temperature of the troposphere decreases with altitude. This is because the air in the troposphere is heated by the Earth's surface. The stratosphere is the second layer of Earth's atmosphere. It extends from about 12 to 50 kilometers (7.5 to 31 miles) above sea level. The temperature of the stratosphere increases with altitude. This is because the ozone layer in the stratosphere absorbs ultraviolet radiation from the Sun. The exosphere is the outermost layer of Earth's atmosphere. It extends from about 500 to 10,000 kilometers (310 to 6,200 miles) above sea level. The temperature of the exosphere decreases with altitude. This is because the air in the exosphere is very thin and there is not enough matter to absorb heat from the Sun.

The correct answer is D. All of the above.

Hydrogen fuel is a renewable resource of energy because it can be produced from water, which is a renewable resource. Wind energy is a renewable resource of energy because it comes from the wind, which is a natural force. Solar energy is a renewable resource of energy because it comes from the sun, which is a natural source of energy.

Here are some additional details about each option:

• Hydrogen fuel is a renewable resource of energy because it can be produced from water, which is a renewable resource. Water is a naturally occurring substance that is constantly being recycled through the Earth's water cycle. This means that there is a virtually unlimited supply of water available for the production of hydrogen fuel.
• Wind energy is a renewable resource of energy because it comes from the wind, which is a natural force. The wind is caused by the uneven heating of the Earth's surface by the sun. This uneven heating creates differences in air pressure, which in turn causes the wind to blow. The wind is a constantly changing force, which means that wind energy is a variable source of energy. However, the wind is a renewable resource, and it can be harnessed to generate electricity.
• Solar energy is a renewable resource of energy because it comes from the sun, which is a natural source of energy. The sun is a star that emits a vast amount of energy in the form of light and heat. This energy can be harnessed to generate electricity, heat water, or power other devices. Solar energy is a clean and sustainable source of energy, and it is becoming increasingly popular as the cost of solar panels decreases.

The correct answer is: All of the above.

Perfect price discrimination is a theoretical concept in which a monopolist can charge each consumer the maximum price they are willing to pay for a good or service. This is also known as first-degree price discrimination.

Second degree price discrimination occurs when a monopolist charges different prices for different units of a good or service, but all consumers pay the same price for each unit. This is also known as block pricing.

Third degree price discrimination occurs when a monopolist charges different prices to different groups of consumers, based on their willingness to pay. This is also known as market segmentation.

All three types of price discrimination can be considered optimal pricing, as they allow the monopolist to extract more surplus from consumers. However, perfect price discrimination is the most efficient form of price discrimination, as it results in the highest level of consumer surplus.

Here is a more detailed explanation of each type of price discrimination:

• Perfect price discrimination is a theoretical concept in which a monopolist can charge each consumer the maximum price they are willing to pay for a good or service. This is also known as first-degree price discrimination. Perfect price discrimination is the most efficient form of price discrimination, as it results in the highest level of consumer surplus. However, it is also the most difficult to achieve, as it requires the monopolist to have perfect information about each consumer's willingness to pay.
• Second degree price discrimination occurs when a monopolist charges different prices for different units of a good or service, but all consumers pay the same price for each unit. This is also known as block pricing. Second degree price discrimination is less efficient than perfect price discrimination, as it results in a lower level of consumer surplus. However, it is easier to achieve than perfect price discrimination, as it does not require the monopolist to have perfect information about each consumer's willingness to pay.
• Third degree price discrimination occurs when a monopolist charges different prices to different groups of consumers, based on their willingness to pay. This is also known as market segmentation. Third degree price discrimination is less efficient than perfect price discrimination, but it is more efficient than second degree price discrimination. It is also easier to achieve than perfect price discrimination or second degree price discrimination, as it does not require the monopolist to have perfect information about each consumer's willingness to pay.

The correct answer is: The southwest monsoon.

The southwest monsoon is a seasonal wind that blows from the southwest towards the northeast across the Indian subcontinent during the summer months. It is caused by the difference in temperature between the land and the ocean. The land heats up faster than the ocean, causing the air above the land to rise. This creates an area of low pressure over the land. The air from the ocean, which is cooler and at a higher pressure, flows in to fill this low pressure area. This flow of air is the southwest monsoon.

The southwest monsoon brings significant rainfall to West Bengal. The state receives an average of 1,200 mm of rainfall during the monsoon season. This rainfall is essential for the agriculture and economy of the state.

The correct answer is: Only I and III are implicit.

The statement "Join X-tuition classes for sure success. Excellent teaching by excellent teachers is our strength." is an advertisement. Advertisements are designed to persuade people to buy a product or service. In this case, the advertisement is trying to persuade people to join X-tuition classes.

The first assumption, "Sure success is desirable," is implicit in the statement. The advertisement is saying that if you join X-tuition classes, you will be successful. This implies that success is something that people want.

The second assumption, "Students expect sure success when they join any tuition class," is not implicit in the statement. The advertisement does not say anything about what students expect when they join a tuition class. It is possible that some students expect sure success, but it is also possible that some students do not expect sure success.

The third assumption, "Just having excellent teachers does not ensure success," is implicit in the statement. The advertisement is saying that X-tuition classes have excellent teachers, but it is also saying that you will be successful if you join X-tuition classes. This implies that excellent teachers are not enough to ensure success.

Therefore, the only assumptions that are implicit in the statement are I and III.
