Question 6

Directions

The critical reasoning question is based on a short passage, an argument, a set of statements, or a plan of action. For each question, select the best answer of the choices given and explain why the chosen answer is the right fit.

Passage: Various studies have recently pointed out the importance of mental health, especially peace of mind, for work productivity and efficiency. They have time and again stressed that sound work comes from a sound mind. Company ABC has decided to go ahead and implement mandatory 15-minute meditation for all employees prior to the start of work.

Which of the following assumptions hold?

  1. AOption (a)

    Meditating for 15 minutes is enough to ensure peace of mind at workplace.

  2. BOption (b)

    Employees resist mental health practices at workplace and consider it an intrusion on their freedom.

  3. COption (c)

    Not a single employee in the company is meditating in their own home.

  4. DOption (d)

    Employees who work often get tired and complain about it.

  5. EOption (e)

    Employees who meditate can sleep better than Employees who don't meditate.

View answer & explanation

Correct answer

Answer: (a)A.

Meditating for 15 minutes is enough to ensure peace of mind at workplace.

Why this answer is correct

Option 1 is a valid assumption. The company is trying out 15-minute meditation prior to work since it feels that it can help employees achieve peace of mind at the workplace.

Option 2 is invalid. If the company feels that employees resist mental health practices at the workplace and consider it an intrusion on their freedom., it will not implement them. Also, it is not related to our question which is the correlation between meditation and peace of mind.

Option 3 is invalid. Employees may or may not be meditating at home but the company feels they have to implement it at the workplace in order to ensure peace of mind at the workplace. As such, the private life of employees is beyond the scope of our passage.

Option 4 is not related to our question which is the correlation between meditation and peace of mind. It is about tiredness from work, which is beyond the scope of our passage.

Option 5 is invalid. As such, the private life of employees and their sleep is beyond the scope of our passage and not the main problem here.

So, only Option 1 is a valid assumption.

Question 7

Directions

In the question below, a passage is given followed by three assumptions numbered I, II and III. An assumption is something supposed or taken for granted. You have to consider the passage and the following assumptions and decide which of the assumptions is implicit in the passage.

Passage:

Every minute, more than 500 hours of video are uploaded to YouTube. YouTube has over 2 billion users, almost one-third of all people on the Internet. The First YouTube Video was uploaded in April 2005, featuring its co-founder Jawed Karim at the San Diego Zoo. YouTube is used to watch music videos, comedy shows, how-to guides, recipes, hacks, and more.

Assumptions:

I: YouTube is a platform where people can upload videos about a variety of things.

II: YouTube is a subsidiary of Google.

III:  YouTube is used by almost one-third of all people on the Internet.

  1. AOption (a)

    Only I

  2. BOption (b)

    Only II

  3. COption (c)

    Only III

  4. DOption (d)

    All except III

  5. EOption (e)

    All follows

View answer & explanation

Correct answer

Answer: (a)A.

Only I

Why this answer is correct

The passage above tells us about the popularity of YouTube and its history as well.

From the last line of the passage, we can assume that YouTube is a platform where 'people' can upload videos about a variety of things.

Hence, assumption I is implicit.

The information provided by the passage is not sufficient enough for us to assume that YouTube is a subsidiary of Google.

Hence, assumption II is not implicit.

The third option is not an assumption as it is a restatement of the fact which is already mentioned in the second line of the passage.

Hence, it cannot be an implicit assumption.

Directions: Study the following information carefully and answer the questions given below:

<br>

Rising concerns about pollution in major Indian cities have led to a dramatic increase in sales of home air purifiers. The air purifier segment, which was earlier limited to select pockets of top metro cities, is firming its foothold in smaller cities, and online channels are emerging as a key facilitator to meet the consumer demand in such places. “The onset of winters, smog situation in various parts of the country and the current concerns around air normally raise the alarm around deteriorating air quality and indoor air pollution. “An air purifier makes the most sense now, owing to the alarming levels of increasing air pollution in major cities around the country,” Eureka Forbes Managing Director and CEO Marzin R. Shroff said.

New Delhi, which has been called the most polluted city in the world by the WHO, is not only the biggest buyer of air purifiers but is also the city that is seeing the fastest growth in sales of these devices.

Question 8

Which of the following is/are definitely an effect(s) of the rising concern of pollution in the context of the passage?

  1. AOption (a)

    The highest demand for air purifiers is from Delhi and its nearby states.

  2. BOption (b)

    Indoor air has been 10 to 30 times more polluted than outside air.

  3. COption (c)

    The concern of government towards citizen has increased

  4. DOption (d)

    The sales of air purifiers has increased up to 200%.

  5. EOption (e)

    Only 1 and 4

View answer & explanation

Correct answer

Answer: (a)A.

The highest demand for air purifiers is from Delhi and its nearby states.

Why this answer is correct

Option 1 is the correct answer. It can be concluded from the given premise that the increase in the level of pollution in the city makes the people aware to buy something which can dampen its effect so people are buying air purifiers. Also, air pollution in Delhi or any city will naturally have some impact on its neighbouring areas.

Option 2 is invalid as the passage does not compare the quality of indoor and outdoor air.

Option 3 is eliminated because no opinion of the government is mentioned in the above passage.

Option 4 is eliminated because the number or percentage of sales of air purifiers is not mentioned in the passage.

Hence, Option 1 is the correct answer.

  1. F and E are facing each other, but F is not a neighbour of D and R. 
  2. E is not sitting at any corner.

 

9.  F is second to the left R. 10. C is third to the right of R.

Here, cases 1(a) and 2(a) will be cancelled out as in those cases there is not any appropriate space left for R.

 

  1. C is sitting seventh to the right of D.
  2. Neither E nor J is neighbour of B

  4. A is neither the neighbour of C nor of H but sitting at the boundary. 
  5. M is neither facing H nor I. 
  6. L is sitting at one of the corners.

Here, case 2(b) will be cancelled out as there is not any appropriate place left for D.

Correct answer

Answer: (b)B.

C 9@ B

Why this answer is correct

By observing the given information, we can conclude that,

@ denotes north 

$ denotes east

% denotes south

& denotes west

In case of odd number: we have to add 15 in the given position.

In case of even number, we have to subtract 15 in the given position.

A 28@B, B 9% C, C 7$ D, D 26%E, E 18& F, F 11&G, G 24% H.

By decoding these expressions, we get

A 28@B: A is 13m is to the north of B

B 9% C: B is 24m is to the south of C

C 7$ D: C is 22m is to the east of D

D 26% E: D is 11m is to the south E

E 18& F: E is 3m is to the west of F

F 11& G: F is 26m is to the west of G

G 24& H: G is 9m is to the west H.

By checking the options:

1) F 5* A: F is northeast 20m to A → False

2) C 9@ B: C is 24m north to B → True

Hence, C 9@ B is the correct answer.

H is father of A, A is father of C, C is sister of B, K is the husband of C, K is father of L, H is husband of G, G is sister of Z.

  1. A & D B,M%L∗C,G B, M \% L * C, G A @ H

A is husband of D, D is mother of B, M is sister of L, L is daughter of C, C is mother of A, A is son of H.

Combininig both we get,

Hence, A is grandfather of M.

  2. BOption (b)

    Data in statement II alone is sufficient to answer the question, while the data in statement I alone is not sufficient to answer the question.

  3. COption (c)

    Data in Statement I alone or in Statement II alone are sufficient to answer the question.

  4. DOption (d)

    Data in both the Statements I and II together are necessary to answer the question.

    Data even in both statements I and II together are not sufficient to answer the question.

View answer & explanation

Correct answer

Answer: (d)D.

Data in both the Statements I and II together are necessary to answer the question.

Why this answer is correct

Given:

  1. H # A # C % B, K & C, K # L, H & G % Z

H is father of A, A is father of C, C is sister of B, K is the husband of C, K is father of L, H is husband of G, G is sister of Z.

  1. A & D B,M%L∗C,G B, M \% L * C, G A @ H

A is husband of D, D is mother of B, M is sister of L, L is daughter of C, C is mother of A, A is son of H.

Combininig both we get,

Now, using statement I

I. C * A, D $ C % B & E, F & N

C is daughter of A, D is father of C, C is sister of B, B is husband of E, F is husband of N.

We cannot determine any relationship between N and E.

Statement II:

II. B # N, B @ A @ G

B is father of N, B is son of A, A is son of G.

            

We cannot determine about N's relationship with B as the gender of N is not known.

Now combining all the information, we get:

Now, we can say that N is daughter of E.

Hence, Data in both the Statements I and II together are necessary to answer the question.

Question 16

Direction: In the question below are given a statement followed by two courses of action numbered I and II. A course of action is a step or administrative decision to be taken for improvement, follow-up or further action regarding the problem, policy, etc. Based on the information given in the statement to be true, then decide which of the suggested courses of action logically follow(s) for pursuing.

Statement:

In India, thousands of people die due to consumption of toxic alcohol. The government has taken certain steps previously but none of them were effective. Faizal, who has been recently appointed as the officer of narcotics department is given the project to suggest some of the schemes/ advice to stop the consumption of toxic alcohol. After certain research, Faizal found that most of the toxic alcohol contains the XYZ component. The XYZ component is mainly used to build certain types of medicines. The permit of XYZ component is accessible to any small companies.

Course of Actions:

I. Faizal suggests allowing the usage of XYZ components to only Pharmaceutical companies.

II. Faizal suggests to publish an order that using XYZ components in alcoholic drinks would be punishable by law.

  1. AOption (a)

    Only I follows.

  2. BOption (b)

    Only II follows.

  3. COption (c)

    Either I or II follows.

  4. DOption (d)

    Neither I nor II follows.

  5. EOption (e)

    Both I and II follow.

View answer & explanation

Correct answer

Answer: (e)E.

Both I and II follow.

Why this answer is correct

Faizal should take both course of actions as XYZ components are used for medical purposes. So, it must be only allowed to used by pharmaceutical companies.

Also, publishing an order to prohibit the use of the XYZ component in alcohol will give a sense of fear to those, who use it illegally.

Hence, both I and II follow.

Question 17

Directions

The question given below consists of a passage, followed by three arguments I, II and III. You have to decide which of the arguments is/are 'strong' arguments and which of the arguments are 'weak' arguments and accordingly choose your answer from the alternatives given below each question.

Passage: The Union Cabinet has cleared the proposal to suspend Insolvency and Bankruptcy Code (IBC) proceedings for bank defaulters for six months with a provision to extend the period for up to one year. This will be applicable for NPAs (non-performing assets) after March 25, 2020. Along with that, there is an exclusion of COVID-19 related debt/defaults from the definition of default under IBC.

Is this a good step from the Government?

Arguments:

I. Yes. The move will offer relief to a lot of companies affected by the COVID-19 crisis.

II. No. This will encourage borrowers to default on their debt obligations and create a bad credit culture in society.

III. No. This will adversely affect loan recoveries of Banks and increase stress on the Banking system.

  1. AOption (a)

    Only I and II are strong

  2. BOption (b)

    Only I and III are strong

  3. COption (c)

    Only II and III are strong

  4. DOption (d)

    Only I is strong

  5. EOption (e)

    All the arguments are strong

View answer & explanation

Correct answer

Answer: (b)B.

Only I and III are strong

Why this answer is correct

Here, the problem is whether the proposal to suspend Insolvency and Bankruptcy Code (IBC) proceedings is a right step or not.

Argument I is strong. Clearly, a lot of companies will be facing Economic stress and subdued business due to the COVID scenario and will be unable to pay their debt obligations. The move will prevent such businesses from being dragged into IBC proceedings.

Argument II is not strong. The Government is not writing off debts of these borrowers to kickstart a bad credit culture. It is only suspending IBC proceedings by 6-18 months. The borrowers are still liable to pay their debt obligations.

Argument III is strong. Suspending IBC will adversely affect the ease of loan recovery of banks and increase the stress on the banking system as the recovery will have to wait until the suspension is revoked.

Hence, only arguments I and III are strong.

Question 27

Directions: The critical reasoning question is based on a short argument, a set of statements, or a plan of action. For each question, select the best answer of the choices given and explain why the chosen answer is the right fit.

Statement: Desertification is a type of land degradation in drylands in which biological productivity is lost due to natural processes or induced by human activities whereby fertile areas become increasingly arider. A huge issue that many countries have is the fact that there are large pockets of land that are going through a process that is known as desertification.

Which of the following statements is/are a possible reason for the increasing desertification?

  1. AOption (a)

    Animal grazing is a huge problem for many areas.

  2. BOption (b)

    Urbanization is providing fewer places for the plants to grow.

  3. COption (c)

    Desertification is reducing the agricultural lands and making them infertile.

  4. DOption (d)

    Both 1 and 2

  5. EOption (e)

    None of these

View answer & explanation

Correct answer

Answer: (d)D.

Both 1 and 2

Why this answer is correct

The passage above discusses the process of desertification. It is becoming a huge problem which is being faced all around the globe.

We need to find options that can be a possible reason for desertification.

The first option talks about animal grazing which can be one of the major reasons for desertification as there are too many animals that are overgrazing in certain spots which makes it difficult for the plants to grow back, which hurts the biome and makes it lose its former green glory.

The second option discusses urbanization and its ill effects upon plants. This is a probable reason for the increasing desertification. Hence, it is also correct.

The third option is more of an effect than a cause of desertification. The lands turning infertile due to desertification are an effect and thus not the correct answer for the above question.

As the statements above mentioned that desertification is a type of land degradation in drylands in which biological productivity is lost due to natural processes or induced by human activities and both Option 1 and 2 are human activities which can cause desertifications.

Hence, both 1 and 2 are correct.

View answer & explanation

Correct answer

Answer: (d)D.

If the data in statement III alone is sufficient to answer the question. 

Why this answer is correct

Code for the given word is as follows;

Statement I: please come here → nm as zh

To find the code for color, we have to find the code for either black or color. So, this statement is not sufficient.

Statement II: he arrived market → st vh re

To find the code for color, we have to find the code for either black or color. So, this statement is not sufficient.

Statement III: everyone like black → ya ck bt

By using this statement we get to know that code for black is 'ck' and the code for color is ld. So, this statement is sufficient.

Hence, If the data in statement III alone is sufficient to answer the question.

Question 33

Which of the following statement can provide the code of "fast"?

Statement I: In the coded language, “please come here” is coded as “nm as zh” and “go to market” is coded as “qx vh pu”.

View answer & explanation

Correct answer

Answer: (c)C.

If the data in statement I and statement II together is sufficient to answer the question. 

Why this answer is correct

Code for the given word is as follows;

Statement I: “please come here” is coded as “nm as zh” and “go to market” is coded as “qx vh pu”.

This statement alone is not sufficient.

Statement II: “he arrived market” is coded as “st vh re” and “not like hat” is coded as “bt kx fn”.

This statement alone is not sufficient.

Statement III: “everyone like black” is coded as “ya ck bt” and “he is fair” is coded as “lz re rf”.

This statement is not sufficient.

By using Statement I and II together,

Code for here is 'nm' and code for arrived is 'st'. So, code for Fast is 'ow'.

Question 38

Directions

The question given below consists of a passage, followed by three arguments I, II and III. You have to decide which of the arguments is/are 'strong' arguments and which of the arguments are 'weak' arguments and accordingly choose your answer from the alternatives given below each question.

Passage: Ministry of Railways has invited bids for operating of passenger train services over 109 routes, using 151 modern trains on the existing rail infrastructure. It is the first step ever in the direction of private investment for running passenger trains over the Indian Railways network.  An estimated ₹30,000 crore investment is expected, beginning from 2023.

Is this a good step from the Indian Railways?

Arguments:

I. Yes. An Expert Committee under the Chairmanship of Bibek Debroy had recommended the step in 2015.

II. Yes.This will improve the quality of services offered by Railways due to a higher focus on customer satisfaction.

III. No. Losses of Private players in Passenger services will have to be cross-subsidized from freight carriage profits of Indian Railways.

  1. AOption (a)

    Only I and II are strong

  2. BOption (b)

    Only II and III are strong

  3. COption (c)

    Only I is strong

  4. DOption (d)

    Only II is strong

  5. EOption (e)

    All the arguments are strong

View answer & explanation

Correct answer

Answer: (a)A.

Only I and II are strong

Why this answer is correct

Here, the problem is whether the step towards private participation in Passenger trains from Indian Railways is right or wrong.

Argument I is strong. Clearly, if an Expert Committee in the matter had recommended the same, it should be a good step.

Argument II is also strong. Customer satisfaction is a major parameter to determine the quality of services. Focussing on customer satisfaction would ensure better quality. Thus, it can be considered a highly desirable outcome of the step. 

Argument III is not a strong one. It is true that currently, Indian railways are cross-subsidizing losses of passenger trains through higher freight tariffs in order to ensure that Passenger tariffs remain low. But the same need not be applicable for trains operated by private players as they can charge higher rates.

Hence, only arguments I and II are strong.

Direction: Statement is given followed by two inferences I and II. You have to consider the statement to be true even if it seems to be at variance from commonly known facts. You have to decide which of the given inferences, if any, follow from the given statement.

Statements:

India’s economy is characterised as a developing market economy. According to world ranking, it is 5th by nominal GDP and 3rd by purchasing power parity. At the beginning of 21st century, annual average GDP growth was 6% to 7%, and from 2014 to 2018. GDP growth moderated to 4.8 per cent from 2019-20, amidst a weak environment for global manufacturing, trade and demand. India's GDP growth is expected to be in the range of 6.0 to 6.5 per cent in 2020-21.

Question 39

Which of the given inferences follows from the given statements?

  1. AOption (a)

    India is in 5th rank by purchasing power parity.

  2. BOption (b)

    The annual average GDP of India was 8.1% in 1998. 

  3. COption (c)

    India’s GDP is expected to grow in 2020-21.

  4. DOption (d)

    India’s GDP is down due to global pandemic.

  5. EOption (e)

    No inference is true.

View answer & explanation

Correct answer

Answer: (c)C.

India’s GDP is expected to grow in 2020-21.

Why this answer is correct

Option (1) cannot be inferred as India is in 3rd rank by purchasing power parity

Option (2) cannot be inferred as there is nothing mentioned about the GDP of 90’s.

Option (3) can be inferred as mentioned in the passage that India's GDP growth is expected to grow in the range of 6.0 to 6.5 per cent in 2020-21.

Option (4) cannot be inferred as there is nothing mentioned about pandemic in the passage.

Hence, option (3) is correct.

Question 40

Directions: Given below is a passage followed by a question. Select the option that best answers the question.

Country B has reported cases of deaths and ailing patients due to an unrecognized disease. Country B has been engaged in biological warfare with country A for 7 years. Country A had recently developed a dangerous virus, Virus X, causing symptoms of severe flu for a week in the host body, eventually leading to the death of the host. The virus only takes effect after 5 days of dormancy. The virus was deported to country B two days ago by one of their special ops. Which of the following statements weakens the doubt of Virus X being the cause of deaths in country B?

  1. AOption (a)

    Country B has poor medical facilities.

  2. BOption (b)

    The special ops assigned to the job deported the virus 4 days before the scheduled time.

  3. COption (c)

    One of the experimental facilities had exploded in country B.

  4. DOption (d)

    The news of deaths was reported on the day the virus had been deported in country B.

  5. EOption (e)

    None of these

View answer & explanation

Correct answer

Answer: (d)D.

The news of deaths was reported on the day the virus had been deported in country B.

Why this answer is correct

Options 1 and 3 have no relation to the given case and thus can be eliminated.

Option 2 only strengthens the fact that Virus X was responsible for the deaths. Only option 4 suggests that the deaths in country B might not be a result of virus X as the virus was deported on the same day as the reported deaths. It is given in the passage that the virus takes at least 5 days to show any symptoms. Hence, option 4 is correct.

Question 41

Directions: The critical reasoning question is based on a short argument, a set of statements, or a plan of action. For each question, select the best answer of the choices given and explain why the chosen answer is the right fit.

Statement:  Employers hire recruitment agencies to find suitable candidates for a particular job profile. Agency recruiters do this by researching the open roles, identifying qualified people, screening the candidates, and providing support to the employer during the selection of the new hire. Recruitment agencies are commonly confused with employment agencies.

Which of the following statements weaken the difference between recruitment agencies and employment agencies?

I: A Recruitment Agency works from the worksite/employer and an Employment Agency works from the jobseeker.

II: A Recruitment Agency typically looks for skilled workers to suit the role available whereas an employment agency will search for a job suitable for the candidate according to his resume.

III: Both recruitment and employment agencies connect the job seekers and the employers

  1. AOption (a)

    Only I and II

  2. BOption (b)

    Only II and III

  3. COption (c)

    Only III

  4. DOption (d)

    All of the above

  5. EOption (e)

    None of the above

View answer & explanation

Correct answer

Answer: (c)C.

Only III

Why this answer is correct

The passage above talks about the recruitment agencies and the task they perform.

The last line of the passage mentions that there is a difference between recruitment agencies and employment agencies but they are generally confused to be the same.

The first statement brings forward an important difference between the recruitment agencies and employment agencies.  Both of them have different category of clients.

Therefore, it cannot weaken the difference between the two.

The second statement brings forward another difference between the recruitment agencies and employment agencies. It differs in the process of its operation which is a major difference.

Hence, it cannot weaken the difference between the two.

The third statement generalizes both the agencies and brings forward a common link between the two.

This will help us to weaken the fact that there is a difference between recruitment and employment agencies.

English Language (35 questions)

Direction: Read the passage given below and answer the following questions.

India is the seventh-largest country in the world by geographical area which is located at South Asia. Moreover, India is the second populous country and the second country which gets the most frequent rainfalls. Then why is India experiencing a water shortage? Unfortunately, there is an ecological unbalance on a global scale. India is one of the eight countries which is seriously facing a sharp increase in water crisis that threatens humans, while a huge percentage of the world has no access to sanitation and clean water. The average person only needs 20 or 30 liters of water, while every Indian uses a big amount of water per day for different purposes than they are supposed to. Additionally, overpopulation and pollution have also been a cause of water poverty in India. Therefore, young children under the age of five make up the 75% of 37.7 million people who are affected by water-borne disease (Khurana 2008). The aim of this project was to create three possible solutions, and finally, the most effective solution is recommended. Thus, several ways to deal with the problem of water shortage in India include harvesting rainwater, watershed management, and river interlinking.

Question 86

Developing farm-based water conservation

Why this answer is correct

The correct answer is 'Developing farm-based water conservation'.

Key Points

  • Let's have a look at the last line of the passage:
  • 'Thus, several ways to deal with the problem of water shortage in India include harvesting rainwater, watershed management, and river interlinking.'
  • ​After a complete analysis of the above statement, it can be concluded that developing farm-based water conservation is not one of the several ways to deal water shortage in India.**
  • Therefore, 'Developing farm-based water conservation' is the correct answer.​

View answer & explanation

Correct answer

Answer: (a)A.

A

Why this answer is correct

The correct answer is 'A'.

Key Points

  • In the first option:
  • The noun following the phrase 'one of the' is always a plural noun, whereas the use of verbs as singular or plural will entirely depend upon the subject of the statement, i.e. singular verb for singular subject and plural verb for the plural subject.
  • Example: Pistachio is one of the few flavors that appeal to me.
  • ​That acts as the subject for the verb 'appeal', and that in this sentence refers to flavors (plural noun) and thus, appeal (plural verb) is used.
  • Hence, an error lies in the first option.
  • Use of 'is' in part A is incorrect.
  • A plural helping verb 'are' is needed in this part.
  • Therefore, 'A' is the correct answer.

Correct sentence: India is one of the eight countries which are seriously facing a sharp increase in water crisis that threatens humans, while a huge percentage of the world has no access to sanitation and clean water. ​

D

Why this answer is correct

The correct answer is 'D'.

Key Points

  • In the fourth option:
  • It appears that the use of a preposition at is incorrect in this context.
  • Generally speaking at is used to describe an exact location or time.
  • Example: *I will meet you at the library. (*the exact place you will meet)
  • It should be replaced by a preposition 'in'.
  • Example: *Please meet me in the library. (*in refers to inside the library)
  • We can also use in to talk about time and place.
  • Therefore, 'D' is the correct answer.

Correct sentence: India is the seventh-largest country in the world by geographical area which is located in South Asia.

Additional Information 

  • A preposition is a word or group of words used before a noun, pronoun, or noun phrase to show direction, time, place, location, spatial relationships, or to introduce an object.
  • Prepositions in English are highly idiomatic.
  • To refer to a direction, use the prepositions "to," "in," "into," "on," and "onto**."**
  • Example: She drove to the store.

                 Don’t ring the doorbell. Come right in(to) the house.

Direction: Read the passage given below and answer the following questions.

India’s economy could contract 7.7 percent in the financial year that ends on March 31, ________ mainly by the coronavirus pandemic and the weeks-long nationwide lockdown to contain the disease, Chief Economic Advisor Krishnamurthy Subramanian has estimated in the Economic Survey 2020-21, tabled in Parliament on Friday. Real GDP growth could be 11 percent in the next financial year, the survey said.

<br>

"Agriculture has remained the silver lining, while contact-based services, manufacturing, and construction sectors were the worst hit by the COVID-19 pandemic,” said the survey. It predicted a V-shaped economic recovery spurred by India's Covid-19 vaccination programme.

The survey sees headline inflation moderating going forward: a development that could open up room for the Reserve Bank of India to resume monetary policy easing to complement fiscal measures to support the economy, said a Bloomberg report.

The Economic Survey, presented in Parliament by the finance minister two days before the Union Budget, analyses the trends in agricultural and industrial production, employment, money supply, and other sectors.

The Union Budget, to be presented by Finance Minister Nirmala Sitharaman on Monday, is expected to increase spending on healthcare, raise levies on a range of imported goods, and likely introduce a Covid-19 cess.

Direction: Read the passage given below and answer the following questions.

According to a report by Greenpeace, 22 out of 30 world’s most-polluted cities are in India. As per recommendations, India requires a minimum of 4,000 air monitoring stations to check air quality. Currently, there are approximately 160 air monitoring stations in India. This implies we have less than 5 percent of the recommended number of air monitoring stations. This inadequacy is a hindrance to policymaking, harming the potential to generate solutions. A base dataset is needed for everything from city planning to new drug development. Air quality monitoring forms the base layer for a number of things, including human health.

Like Peter Drucker said: “If you cannot measure it, you cannot solve it”. AI can help solve this problem. Accurate computation of air quality not only requires combining existing air monitoring infrastructure with satellite data but also factoring in human activities such as traffic, construction, garbage burning, industrial source apportionment, and population density. A feature engineered AI can be designed to utilise the above factors to accurately compute a geospatial interpolation of air quality data. The advantage of such an approach is that it provides a distributed coverage of high spatiotemporal resolution in near real time.

In Delhi, the number of air monitoring stations has increased in recent years. This has provided us with research-backed sources of air pollution within a few parts of the capital. By understanding the sources of pollution, AI can be further used to track and predict the growth and reduction of air pollution. For example, we could monitor whether an increase in industrial production is directly proportional to air pollution, or a decrease in vehicles is related to a reduction. These decisions could be evaluated by AI, allowing appropriate actions to be initiated. AI can also help in modelling the chemical reactions between pollutants. Algorithms like Atmospheric Transport Modelling System (ATMoS) helps understand PM2.5 concentrations. Additionally, there are advanced algorithms that help in understanding and predicting smog, haze, visibility, and observe meteorological interventions as well as manage air quality better.

Read the given passage and choose the correct answer for the questions given below. 

The impacts of our ever-growing economy have become so___1___ (stark, clear, opaque) and so widespread that they are by any___2___(demented, sane, rough) measure, portents to catastrophe. Whether it’s the fact that Antarctic ice is now melting three times faster than we thought or the unfolding “biological___3___(destruction, construction, annihilation) ” that has already wiped out 50% of all animals and up to 75% of all insects, or the fact that, in spite of all this, we are pumping out CO2 at record levels, it takes willful ignorance or a blinding ideology to deny the severity of the crisis. This creates a terrible paradox: Economic growth keeps economies stable today, but threatens not just future growth but medium-term social and civilizational___4___(cohesion, solidarity, confusion) and ultimately the very capacity of this biosphere to sustain life. A paper published in the Proceedings of the National Academy of Sciences last year suggested that “the window for effective action is very short, probably two or three decades at most.” And that even this dire___5___(triumph, prediction, plummet) is considered “conservative” by the authors, “given the increasing trajectories of the drivers of extinction.” In terms of practical politics, that means acting immediately, preferably yesterday. Most politicians deal with this___6___(paradox, redux, coarse) by ignoring it. It’s by far the easiest option; one afforded every incentive and reward by this political economy and the beliefs that underpin it. This belief system has been dominant for a long time now. We are, as a society, deeply comfortable with it, which means many of its core___7___(assumptions, beliefs, dearth) are considered unassailable–too obvious to question. The most profound being this idea that growth is always good.

Why this answer is correct

The correct answer is Only 2.

Key Points

  • The phrase which we should choose to connect the sentences is only 2. 
  • The word 'however' is used when we try to say 'but despite that'. So, the phrase 'However some issues' would join the sentences appropriately.
  • 'When' is used to express 'during the time that'. Therefore, we should not choose the phrase 'When some issues' to join the given sentences.
  • 'Whenever' means 'at whatever time'. So, the phrase 'Whenever social issues' is not appropriate for the sentences.
<br>

The sentence after using the phrase is: Social issues are distinguished from economic issues; however, some issues have both social and economic aspects.

Why this answer is correct

The correct answer is only 2.

Key Points

  • The phrase which we can use to connect the given sentences is only 2.
  • When 'even if' is used, we try to express 'despite the fact that'. Therefore, 'even if' should be chosen to form a grammatically and contextually appropriate sentence.
  • 'If' is used to introduce a conditional clause and to form a conditional sentence. Clearly, we should not choose 'if' to connect the given sentences.
  • 'When' is used to express 'during the time'. So, we cannot choose 'when' to form a grammatically and contextually correct sentence.

The sentence after using the phrase is: You should always help others even if they are not your friends.

The correct answer is 'Both 1 and 3'.

Key Points

  • The phrases which we should use to connect the statements is both 1 and 3.

  • So, the connectors 'as a consequence' and 'as a result' needs to be used to join the two statements. Using these connectors answers the question "how did Varun die?'
  • 'in contrast' is used to express difference. Hence it cannot be used to join the given statements.

The sentence after using the phrases is : Varun died as a consequence/as a result of an accident.​

View answer & explanation

Correct answer

Answer: (b)B.

Q

Why this answer is correct

The correct sentence is Q.

The first sentence must introduce a new concept without any prior reference and the best option for this is sentence S which introduces the discussion on diamonds. The second sentence is given and this extends the discussion by naming the interesting aspects of diamonds. The third sentence must either continue this description or introduce a related sub-topic and here, since there is one more sentence T which describes diamonds, we include that as the third sentence. Because the third sentence talks about diamond hardness, the fourth sentence can continue to elaborate on this and this is achieved in sentence P. Hence this is the fourth sentence. The fifth sentence is given and it introduces the importance of diamonds in history which is a new sub-topic. Sentence 6 must extend this sub-topic and this is done in Q where details about historic events and conquests are mentioned, hence Q is sentence 6. Sentence R is the last sentence because it includes the word 'also' which indicates that sentence 6 must have already introduced other historic events, which is the case.  

So the correct order of sentences is S2TP5QR. Thus, option 2 is the correct answer.

Data Analysis & Interpretation (35 questions)

Examine the following pattern of the series carefully and answer the following question.

Example: Find the wrong number in the following series and following the pattern, find the fourth term in the series starting with the wrong number.

32, 34, 36, 39, 40, 42

Here, the pattern of the series is the difference of 2.

Here the wrong number in the series is 39

So, starting with ‘39’ the series will be 39, 41, 43, 45

Therefore, the fourth term is 45.

Question 121

Similarly, following the above pattern, find the second term in the 2nd series.

  5. EOption (e)

    369

View answer & explanation

Correct answer

Answer: (c)C.

459

Why this answer is correct

Pattern of the series is:

9 × 2 + 1 = 19

19 × 3 + 1 = 58

58 × 4 + 1 = 233

233 × 5 + 1 = 1166

1166 × 6 + 1 = 6997

Therefore wrong number in the series is 229. 

So, starting with 229, the series will be 229, 459, 1378, 5513.

∴ The Second term in the 2nd series is 459.

Question 122

Similarly, following the above pattern, find the third term in the 2nd series.

78, 80, 83, 88, 95, 104

  5. EOption (e)

    105

View answer & explanation

Correct answer

Answer: (a)A.

109

Why this answer is correct

Pattern of the series is:

78 + 2 = 80

80 + 3 = 83

83 + 5 = 88

88 + 7 = 95

95 + 11 = 106

Therefore wrong number in the series is 104.

So, starting with 104, the series will be 104, 106, 109, 114.

∴ The Third term in the 2nd series is 109.

Confusion Points

There is a possibility with the logic.

Here logic used is prime no. 2,3,5, 7 ,11 But difference given is 2,3,5,7,9

So one can think it is an odd no series and can consider 1st term as the wrong term to make the difference, 1 which is odd

But there is no option for 83 which will be third term in the 2nd series if starting from 79.

Question 123

Similarly, following the above pattern, find the fourth term in the 2nd series.

88, 90, 94, 102, 108, 118

  1. AOption (a)

    122

  2. BOption (b)

    132

  3. COption (c)

    108

  4. DOption (d)

    104

  5. EOption (e)

    114

View answer & explanation

Correct answer

Answer: (e)E.

114

Why this answer is correct

Pattern of the series is:

88 + 2 = 90

90 + 4 = 94

94 + 6 = 100

100 + 8 = 108

108 + 10 = 118

Therefore wrong number in the series is 102.

So, starting with 102, the series will be 102, 104, 108, 114, 122, 132

∴ The fourth term in the 2nd series is 114.

Question 124

In the following series, one of the terms given is wrong which is denoted by N. 

Series : 85, 175, 355, 715, 1380

Find that term and mark the statement whose value is equivalent to N30+1{N \over30 } + 1 and mark that as your answer.

  1. AOption (a)

    It is a prime number.

  2. BOption (b)

  3. COption (c)

    Sum of digit is less than 9

  4. DOption (d)

    Product of digits is more than 30

  5. EOption (e)

    None of these

View answer & explanation

Correct answer

Answer: (a)A.

It is a prime number.

Why this answer is correct

Series : 85, 175, 355, 715, 1380

Pattern of the series is:

85 × 2 + 5 = 175

175 × 2 + 5 = 355

355 × 2 + 5 = 715

715 × 2 + 5 = 1435

∴ The Wrong term in the series is 1380.

N = 1380

N30+1{N \over30 } + 1 = 47

∴ 47 is a prime number.

In a bag, there are 17 red balls, some green, and some blue balls. The probability of drawing a green ball is (1/7) more than that of a red ball. The probability of drawing a blue ball is (1/21) more than that of a red ball.

Correct answer

Answer: (c)C.

63

Why this answer is correct

Shortcut Trick

Let Total Balls be T. Given Red (R) = 17.

P(Green) − P(Red) = 1/7 ⇒ (G − 17)/T = 1/7 ⇒ T = 7(G − 17)

P(Blue) − P(Red) = 1/21 ⇒ (B − 17)/T = 1/21 ⇒ T = 21(B − 17)

Equating T: 7(G − 17) = 21(B − 17) ⇒ G − 17 = 3B − 51 ⇒ G = 3B − 34

Total T = 17 + G + B = 17 + (3B − 34) + B = 4B − 17. Also T = 21B − 357.

21B − 357 = 4B − 17 ⇒ 17B = 340 ⇒ B = 20. Then T = 21(20 − 17) = 63.

∴ The correct answer is 63 balls.

Alternate Method

Given: Number of Red balls = 17. Let Green balls = g and Blue balls = b.

Formula: Probability P(E) = Outcomes / Total

⇒ P(Green) = P(Red) + 1/7

⇒ g/T = 17/T + 1/7 ⇒ (g − 17)/T = 1/7 ⇒ 7g − 119 = T ... (Eq 1)

⇒ P(Blue) = P(Red) + 1/21

⇒ b/T = 17/T + 1/21 ⇒ (b − 17)/T = 1/21 ⇒ 21b − 357 = T ... (Eq 2)

⇒ From Eq 1 & 2: 7g − 119 = 21b − 357 ⇒ 7g − 21b = −238 ⇒ g − 3b = −34 ... (Eq 3)

⇒ Also, T = 17 + g + b. Substitute in Eq 1: 7g − 119 = 17 + g + b ⇒ 6g − b = 136 ... (Eq 4)

⇒ Solving Eq 3 & 4: g = 26, b = 20

⇒ Total Balls = 17 + 26 + 20 = 63

∴ The correct answer is 63 balls.

Correct answer

Answer: (c)C.

20

Why this answer is correct

Shortcut Trick

Let Total balls be T. Given Red balls = 17.

Difference in probabilities: P(Green) − P(Red) = 1/7 ⇒ (g − 17)/T = 1/7 ⇒ 7g − 119 = T.

Difference in probabilities: P(Blue) − P(Red) = 1/21 ⇒ (b − 17)/T = 1/21 ⇒ 21b − 357 = T.

Equating T: 7g − 119 = 21b − 357 and substituting T = 17 + g + b leads to b = 20.

∴ The correct answer is 20 balls.

Alternate Method

Given: Red balls = 17, Green balls = g, Blue balls = b.

Formula Used: Probability P(E) = Number of favorable outcomes ÷ Total outcomes.

⇒ P(Green) = P(Red) + 1/7

⇒ g/T = 17/T + 1/7 ⇒ (g − 17)/T = 1/7 ⇒ T = 7g − 119 --- (i)

⇒ P(Blue) = P(Red) + 1/21

⇒ b/T = 17/T + 1/21 ⇒ (b − 17)/T = 1/21 ⇒ T = 21b − 357 --- (ii)

⇒ From (i) and (ii): 7g − 119 = 21b − 357 ⇒ 7g − 21b = −238 ⇒ g − 3b = −34 ⇒ g = 3b − 34

⇒ Substitute g and T in T = 17 + g + b:

⇒ 21b − 357 = 17 + (3b − 34) + b

⇒ 21b − 357 = 4b − 17

⇒ 17b = 340 ⇒ b = 20

∴ The correct answer is 20 balls.

View answer & explanation

Correct answer

Answer: (d)D.

1 : 2

Why this answer is correct

From the given pie charts, we have:

(N + 5) + N + (N + 20) + 2N = 100

⇒ N = 15

Also, M + 20 + (M + 10) + 40 = 100

⇒ M = 15

Let the total number of cookies sold be x

Also, total number of cookies sold by A = (20/100) × x = 0.2x

Also, the number of Butterscotch cookies sold by A = 110 

So, the number of chocolate cookies sold by A = 0.2x – 110

Hence, 0.2x – 110 = (15/100) × total number of chocolate cookies      ----(i)

Similarly,

Also, total number of cookies sold by B = (15/100) × x = 0.15x

Also, the number of Butterscotch cookies sold by B = 30 

So, the number of chocolate cookies sold by B = 0.15x – 30

Hence, 0.15x – 30 = (20/100) × total number of chocolate cookies      ----(ii)

Multiply equation (i) by 3, 

⇒ 0.6x – 330 = (45/100) × total number of chocolate cookies      ----(iii) 

and equation (ii) by 4:

⇒ 0.6x – 120 = (80/100) × total number of chocolate cookies      ----(iv)

Subtract equation (iii) from equation (iv)

⇒ -120 + 330 = (0.8 – 0.45) × total number of chocolate cookies 

⇒ Total number of chocolate cookies = 210/0.35 = 600

Also, from the pie chart of total cookies,

200 = (20/100) × total cookies

⇒ Total cookies = 1000

Hence, we can tabulate the percentage of cookies for each type as:

CompanyChocolate CookiesButterscotch flavor cookiesTotal Cookies
A(15/100) × 600 = 90110200
B(20/100) × 600 = 12030150
C(25/100) × 600 = 150200(35/100) × 1000 = 350
D(40/100) × 600 = 24060(30/100) × 1000 = 300

 

∴ The ratio of chocolate flavor cookies sold by company C to the total cookies sold by D = 150/300 = 1 ∶ 2

Answer: (b)B.

75%

Why this answer is correct

From the given pie charts, we have:

(N + 5) + N + (N + 20) + 2N = 100

⇒ N = 15

Also, M + 20 + (M + 10) + 40 = 100

⇒ M = 15

Let the total number of cookies sold be x

Also, total number of cookies sold by A = (20/100) × x = 0.2x

Also, the number of Butterscotch cookies sold by A = 110 

So, the number of chocolate cookies sold by A = 0.2x – 110

Hence, 0.2x – 110 = (15/100) × total number of chocolate cookies      ----(i)

Similarly,

Also, total number of cookies sold by B = (15/100) × x = 0.15x

Also, the number of Butterscotch cookies sold by B = 30 

So, the number of chocolate cookies sold by B = 0.15x – 30

Hence, 0.15x – 30 = (20/100) × total number of chocolate cookies      ----(ii)

Multiply equation (i) by 3, 

⇒ 0.6x – 330 = (45/100) × total number of chocolate cookies      ----(iii) 

and equation (ii) by 4:

⇒ 0.6x – 120 = (80/100) × total number of chocolate cookies      ----(iv)

Subtract equation (iii) from equation (iv)

⇒ -120 + 330 = (0.8 – 0.45) × total number of chocolate cookies 

⇒ Total number of chocolate cookies = 210/0.35 = 600

Also, from the pie chart of total cookies,

200 = (20/100) × total cookies

⇒ Total cookies = 1000

Hence, we can tabulate the percentage of cookies for each type as:

CompanyChocolate CookiesButterscotch flavor cookiesTotal Cookies
A(15/100) × 600 = 90110200
B(20/100) × 600 = 12030150
C(25/100) × 600 = 150200(35/100) × 1000 = 350
D(40/100) × 600 = 24060(30/100) × 1000 = 300

 

Total cookies sold by A and B = 200 + 150 = 350

Butterscotch cookies sold by C = 200

So, the required percentage = [(350 – 200)/200] × 100 = 75%

Why this answer is correct

From the given pie charts, we have: 

(N + 5) + N + (N + 20) + 2N = 100

⇒ N = 15

Also, M + 20 + (M + 10) + 40 = 100

⇒ M = 15

Let the total number of cookies sold be x

Also, total number of cookies sold by A = (20/100) × x = 0.2x

Also, the number of Butterscotch cookies sold by A = 110 

So, the number of chocolate cookies sold by A = 0.2x – 110

Hence, 0.2x – 110 = (15/100) × total number of chocolate cookies      ----(i)

Similarly,

Also, total number of cookies sold by B = (15/100) × x = 0.15x

Also, the number of Butterscotch cookies sold by B = 30 

So, the number of chocolate cookies sold by B = 0.15x – 30

Hence, 0.15x – 30 = (20/100) × total number of chocolate cookies      ----(ii)

Multiply equation (i) by 3, 

⇒ 0.6x – 330 = (45/100) × total number of chocolate cookies      ----(iii) 

and equation (ii) by 4:

⇒ 0.6x – 120 = (80/100) × total number of chocolate cookies      ----(iv)

Subtract equation (iii) from equation (iv)

⇒ -120 + 330 = (0.8 – 0.45) × total number of chocolate cookies 

⇒ Total number of chocolate cookies = 210/0.35 = 600

Also, from the pie chart of total cookies,

200 = (20/100) × total cookies

⇒ Total cookies = 1000

Hence, we can tabulate the percentage of cookies for each type as:

CompanyChocolate CookiesButterscotch flavor cookiesTotal Cookies
A(15/100) × 600 = 90110200
B(20/100) × 600 = 12030150
C(25/100) × 600 = 150200(35/100) × 1000 = 350
D(40/100) × 600 = 24060(30/100) × 1000 = 300

 

So, we get:

x + 15 = 90 

⇒ x = 75

Similarly, y – 25 = 120

⇒ y = 145

∴ x ∶ y = 75 ∶ 145 = 15 ∶ 29

33.33%

Why this answer is correct

From the given pie charts, we have:

(N + 5) + N + (N + 20) + 2N = 100

⇒ N = 15

Also, M + 20 + (M + 10) + 40 = 100

⇒ M = 15

Let the total number of cookies sold be x

Also, total number of cookies sold by A = (20/100) × x = 0.2x

Also, the number of Butterscotch cookies sold by A = 110 

So, the number of chocolate cookies sold by A = 0.2x – 110

Hence, 0.2x – 110 = (15/100) × total number of chocolate cookies      ----(i)

Similarly,

Also, total number of cookies sold by B = (15/100) × x = 0.15x

Also, the number of Butterscotch cookies sold by B = 30 

So, the number of chocolate cookies sold by B = 0.15x – 30

Hence, 0.15x – 30 = (20/100) × total number of chocolate cookies      ----(ii)

Multiply equation (i) by 3, 

⇒ 0.6x – 330 = (45/100) × total number of chocolate cookies      ----(iii) 

and equation (ii) by 4:

⇒ 0.6x – 120 = (80/100) × total number of chocolate cookies      ----(iv)

Subtract equation (iii) from equation (iv)

⇒ -120 + 330 = (0.8 – 0.45) × total number of chocolate cookies 

⇒ Total number of chocolate cookies = 210/0.35 = 600

Also, from the pie chart of total cookies,

200 = (20/100) × total cookies

⇒ Total cookies = 1000

Hence, we can tabulate the percentage of cookies for each type as:

CompanyChocolate CookiesButterscotch flavor cookiesTotal Cookies
A(15/100) × 600 = 90110200
B(20/100) × 600 = 12030150

D(40/100) × 600 = 24060(30/100) × 1000 = 300

 

So, total number of chocolate cookies sold by all the companies together = 90 + 120 + 150 + 240 = 600

And total number of Butterscotch cookies sold by all the companies together = 110 + 30 + 200 + 60 = 400 

**∴ The required percentage (**less) = [(600 – 400)/600] × 100 = 33.33%

Answer: (d)D.

16.67%

Why this answer is correct

From the given pie charts, we have:

(N + 5) + N + (N + 20) + 2N = 100

⇒ N = 15

Also, M + 20 + (M + 10) + 40 = 100

⇒ M = 15

Let the total number of cookies sold be x

Also, total number of cookies sold by A = (20/100) × x = 0.2x

Also, the number of Butterscotch cookies sold by A = 110 

So, the number of chocolate cookies sold by A = 0.2x – 110

Hence, 0.2x – 110 = (15/100) × total number of chocolate cookies      ----(i)

Similarly,

Also, total number of cookies sold by B = (15/100) × x = 0.15x

Also, the number of Butterscotch cookies sold by B = 30 

So, the number of chocolate cookies sold by B = 0.15x – 30

Hence, 0.15x – 30 = (20/100) × total number of chocolate cookies      ----(ii)

Multiply equation (i) by 3, 

⇒ 0.6x – 330 = (45/100) × total number of chocolate cookies      ----(iii) 

and equation (ii) by 4:

⇒ 0.6x – 120 = (80/100) × total number of chocolate cookies      ----(iv)

Subtract equation (iii) from equation (iv)

⇒ -120 + 330 = (0.8 – 0.45) × total number of chocolate cookies 

⇒ Total number of chocolate cookies = 210/0.35 = 600

Also, from the pie chart of total cookies,

200 = (20/100) × total cookies

⇒ Total cookies = 1000

Hence, we can tabulate the percentage of cookies for each type as:

CompanyChocolate CookiesButterscotch flavor cookiesTotal Cookies
A(15/100) × 600 = 90110200
B(20/100) × 600 = 12030150
C(25/100) × 600 = 150200(35/100) × 1000 = 350
D(40/100) × 600 = 24060(30/100) × 1000 = 300

 

∴ The required percentage = [60/(120 + 240)] × 100 = 16.67%

    60%

  5. EOption (e)

    50%

View answer & explanation

Correct answer

Answer: (d)D.

60%

Why this answer is correct

Let the number of employees in the company during each of the year be x

So, the number of managers in the year 2005 = (80/100)x = 0.8x

Among them, the number of male managers = (5/8) × 0.8x = 0.5x

Similarly,

So, the number of managers in the year 2006 = (50/100)x = 0.5x

Among them, the number of male managers = (2/5) × 0.5x = 0.2x

So, the percentage decrease in the number of male managers = [(0.5x – 0.2x)/0.5x] × 100 = 60%

Question 133

If the number of employees working in the company in 2005 is 1000. Also, it is known that the number of male workers is the same as the number of female workers in 2005. Then what is the difference between the number of female workers and the number of female managers in the year 2005?

  1. AOption (a)

    400

  2. BOption (b)

    200

  3. COption (c)

    100

  4. DOption (d)

    300

  5. EOption (e)

    None of these

View answer & explanation

Correct answer

Answer: (b)B.

200

Why this answer is correct

Number of employees in the company in 2005 = 1000

So, total number of managers in 2005 = (80/100) × 1000 = 800

Hence, the number of workers = 1000 – 800 = 200

Now, the number of male and female workers is equal.

So, the number of female workers in 2005 = 200/2 = 100

Also, the number of female managers = (3/8) × 800 = 300

Hence, the required difference = 300 – 100 = 200

∴ The difference between the number of female workers and the number of female managers in the year 2005 is 200

Question 134

If the number of male managers in the year 2003 is 480, and the number of female managers in the year 2005 is 450. Then find the ratio of the number of employees in the company in 2003 and that in the year 2005.

  1. AOption (a)

    3 ∶ 2

  2. BOption (b)

    4 ∶ 3

  3. COption (c)

    2 ∶ 3

  4. DOption (d)

    3 ∶ 4

  5. EOption (e)

    None of these

View answer & explanation

Correct answer

Answer: (b)B.

4 ∶ 3

Why this answer is correct

Ratio of male managers to female managers in 2003 = 3 ∶ 2

The number of male managers in 2003 = 480

Hence, the number of female managers in 2003 = 480 × (2/3) = 320

So, the total number of managers in 2003 = 480 + 320 = 800

Percentage of the total employees as managers in 2003 = 40%

So, (40/100) × total employees in 2003 = 800

⇒ Total employees in 2003 = 800 × (100/40) = 2000

Similarly, we have:

Ratio of male managers to female managers in 2005 = 5 ∶ 3

The number of female managers in 2005 = 450

Hence, the number of male managers in 2005 = 450 × (5/3) = 750

So, the total number of managers in 2005 = 450 + 750 = 1200

Percentage of the total employees as managers in 2005 = 80%

So, (80/100) × total employees in 2005 = 1200

⇒ Total employees in 2005 = 1200 × (100/80) = 1500

Hence, the required ratio = 2000 ∶ 1500 = 4 ∶ 3

Question 135

If the number of workers in the year 2008 is 1400, and the number of total workers in the company has doubled since 2007; then find the number of managers in the company in 2007.

  1. AOption (a)

    1500

  2. BOption (b)

    1200

  3. COption (c)

    1300

  4. DOption (d)

    1000

  5. EOption (e)

    None of these

View answer & explanation

Correct answer

Answer: (c)C.

1300

Why this answer is correct

Number of workers in 2008 = 1400

As the number of total workers has doubled in 2008 from 2007,

Number of workers in 2007 = 1400/2 = 700

Also, the percentage of the total employees working as managers in 2007 = 65%

Hence, the percentage of the total employees working as workers in 2007 = 100 – 65 = 35%

So, 35% of the total employees in 2007 = 700

⇒ Total employees in 2007 = 700 × (100/35) = 2000

So, the number of managers in the year 2007 = 2000 – 700 = 1300

Question 136

If the total number of workers remains the same in the year 2005 and the year 2006, then find the ratio between the total number of male managers in these two years.

  1. AOption (a)

    32 ∶ 125

  2. BOption (b)

    10 ∶ 13

  3. COption (c)

    13 ∶ 10

  4. DOption (d)

    25 ∶ 4

  5. EOption (e)

    None of these

View answer & explanation

Correct answer

Answer: (d)D.

25 ∶ 4

Why this answer is correct

Let the total number of employees in the the year 2005 be x

So, the total number of managers in 2005 = (80/100) × x = 0.8x

⇒ Total number of workers in 2005 = x – 0.8x = 0.2x

Hence, the number of male managers in 2005 = (5/8) × 0.8x = 0.5x

And the total number of employees in the the year 2006 be y

Also, So, the total number of managers in 2006 = (50/100) × y = 0.5y

⇒ Total number of workers in 2006 = y – 0.5y = 0.5y

Hence, the number of male managers in 2006 = (2/5) × 0.5y = 0.2y

As the number of workers is the same, we get:

0.2x = 0.5y

⇒ x = 2.5y      ----(i)

Using equation(i), the required ratio will become:

(0.5 × 2.5y)/0.2y = 25/4

∴ The reuqired ratio between the number of male managers in 2005 and 2006 is 25 ∶ 4

Question 137

Consider the table below and answer the following question.

In the table given below, there are two columns namely A and B.

In column A, Three figures are given with certain information about them.

In column B, certain values are given. 

AB
Figure 1: A cone is mounted over a hemisphere. The volume of the figure is 2156 cm31) Radius = 7 cm
Figure 2: A cylinder is shown with a volume of 1078 cm32) Radius = 14 cm

  4. DOption (d)

    Both (1) and (2)

  5. EOption (e)

    All of the above

View answer & explanation

Correct answer

Answer: (e)E.

All of the above

Why this answer is correct

Concept used:

Volume of cone = (1/3) × πr2h

The volume of cylinder = πR2H

Volume of hemisphere = (2/3) × πr3

Calculation:

From column B, row 3, let us find out the radius corresponding to the given circumference.

Circumference = 2πr = 44

Or, r = 44 × 7/44 = 7 cm.

From this, we can conclude that, in column B, row 1 and row 3 are equal.

Our table will look like this:

AB
Figure 1: A cone is mounted over a hemisphere. The volume of the figure is 2156 cm31) Radius = 7 cm
Figure 2: A cylinder is shown with a volume of 1078 cm32) Radius = 14 cm
Figure 3: A hemisphere with its circular part facing upwards.3) Circumference = 44 cm Or, Radius = 7 cm
<br>

Now, Volume of figure 1 = 2156 cm 3

Volume of figure 1 = volume of hemisphere + volume of cone

2156 = (1/3) × πr2h + (2/3) × πr3

Let us take radius r = 7 cm and observe the value of h.

2156 = (1/3) × (22/7) × 72 × h + (2/3) × (22/7) × 73

2156 = (154/3) × h + 2156/3

Or, h = 28 cm

Now, let's go through the options and see what values are obtained for figure 2, where the radius of figure 1 is taken as 7 cm.

We have 2 possibilities, namely, 2 – 2 and 2 – 3.

As 1 and 3 of column B are the same, we need not do option (c) as this is the same as option (b) of the question.

Let us take radius r = 14 cm and observe the value of h of the cylinder.

The volume of cylinder = πR2H

1078 cm3 = (22/7) × 142 × H

H = 1078 × 7/4312 = 1.75 cm

Then, difference between height of cone and cylinder = 28 – 1.75 > 20

So, this option satisfies the condition.

Now, 

Let us take radius r = 7 cm and observe the value of h of the cylinder.

The volume of cylinder = πR2H

1078 cm3 = (22/7) × 72 × H

H = 1078/(22 × 7) = 7

Then, the difference between the height of cone and cylinder = 28 – 7 > 20

So, this option satisfies the condition.

Looking at the options, it is clear that, all options satisfy the conditions 

∴ The all the options satisfy the given condition.

Correct answer

Answer: (b)B.

2 - 1, 1 - 3 

Why this answer is correct

Concept used:

Volume of cone = (1/3) × πr2h

The volume of cylinder = πR2H

Volume of hemisphere = (2/3) × πr3

Calculation:

Our table will look like this:

AB
Figure 1: A cone is mounted over a hemisphere. The volume of the figure is 2156 cm31) Radius = 7 cm
Figure 2: A cylinder is shown with a volume of 1078 cm32) Radius = 14 cm
Figure 3: A hemisphere with its circular part facing upwards.3) Circumference = 44 cm Or, Radius = 7 cm
<br>

Ratio of the height of figure 1 to figure 2 = 5 ∶ 1

⇒ (r + h) : H = 5 : 1

⇒ r + h = 5r                            (r = H, given)

⇒ r : h = 1 : 4

Now, Volume of figure 1 = 2156 cm 3

⇒ 2156 = (1/3) × π(x)2(4x)+ (2/3) × π(x)3

⇒ 343 = x3

⇒ x = 7 

⇒ Radius of figure 1 = height of cylinder = 7 cm, calculating for radius of cylinder, we get

⇒ Radius of cylinder = (1078 × 7/22 × 7)1/2 = 7 cm, which is given in only option 2

Now, Circumference = 2πr

⇒ Circumference = 2 × (22/7) × 7

⇒ Circumference = 44 cm

∴ The required solution obtained when 2 - 1, 1 - 3 is applied.

55%

Why this answer is correct

Given:

VillageTotal population% of literates% of literate female% of illiterate male
Q35500402540
R30200306050
T45000835535
<br>

Calculation:

Number of female illitrates from Q and R = Number of illitrates from Q  × 60% + Number of illitrates from R × 70% × 50% 

Number of illitrates from Q = Total population × 60% = 35500 × 60% = 21300

Number of illitrates from R = Total population × 70% = 30200 × 70% = 21140

Number of female illitrates from Q and R = 21300 × 60% + 21140 × 50% = 23350

Number of females who are not attending from village Q and R = 45% × number of females from Q and R = 45% × 23350 = 10508

Total number of people who attend the program from Q and R = Total illiterates from Q and R - Number of females who are not attending from village Q and R

Total number of people who attend the program from Q and R = 21300 + 21140 - 10508 = 31932

Total number of people who attend the program = illiterates from T + 31932 = 45000 × 17% + 31932 = 39582

Total number of males who attend the program = Q's illiterats × 40% + R's illiterates × 50% + T's illiterates × 35% 

Total number of males who attend the program = 21300 × 40% + 21140 × 50% + 7650 × 35% = 21768

Percentage of males in total attended = 21768/39582 × 100 = 55%

∴ Percentage of males in total attended people is 55%.

85.7%

Why this answer is correct

Given:

VillageTotal population% of literates% of literate female% of illiterate male
S25750723545
<br>

Calculation:

Total literates = total population × 72% = 18,540

Number of female literates = total literates × 35% = 18540 × 35% = 6489

Number of male literates = total literates - female literates = 18540 - 6489 = 12,051

Difference between male and female literates = 12051 - 6489 = 5562

Percentage of male literates more than female literates = 5562/6489 × 100 = 85.7%

∴ Male literates are 85.7% more than female literates.

P44500204530
<br>

Calculation:

Number of literate females = total number of literates × 45% = 44500 × 20% × 45%  =4005

Number of literate females working = 65% × number of literate females = 65% × 4005 = 2603.25

Total wages obtained by all = 600 × 2603.25 = Rs. 15,61,950

∴ The total wages obtained by females is Rs. 15,61,950.

<br>

Amount of rice and sugar given to villagers = 3 kg rice and 2 kg sugar

Calculation:

Number of literate females = 30200 × 30% × 60%

Number of male literates = 30200 × 30% × 40%

The total amount of rice got by the females = 3 ×  30200 × 30% × 60%      ----(1)

The total amount of sugar got by males = 30200 × 30% × 40%      ----(2)

The ratio of (1) ∶ (2) = 30200 × 30% × 60% × 3 ∶ 30200 × 30% × 40% × 2

The ratio of (1) ∶ (2) = 9 ∶ 4

∴ The ratio of the total amount of rice received by literate females to the total amount of sugar received by literate males is 9 ∶ 4.

Confusion Points The literate males will not be calculated from the illiterate male population but from the literate female as literate female+literal male = total literate population.

Why this answer is correct

Given:

Percentage of illiterates who became literates = 25%

VillageTotal population% of literates% of literate female% of illiterate male
Q35500402540
<br>

Calculation:

Number of illiterates who became literates = 25% × 35500 × 60% = 5325

Then, total number of literates = 35500 × 40% + 5325 = 19,525

Number of illiterates = 75% × 35500 × 60% = 15,975

Percentage of literates = 19,525/35500 × 100 = 55% 

Percentage of illiterates = 15,975/35500 × 100 = 45%

Ratio of Percentage of literates to illiterates = 55 ∶ 45 = 11 ∶ 9

∴ The required ratio is 11 ∶ 9.

Statement I: Effective CI % for 2 years at 25% = 25 + 25 + (25×25)/100 = 56.25%. SI % for 1 year at 5% = 5%. Difference (51.25%) = ₹250. Principal can be found.

Statement II: Says the sum gets 'two more than its triple' but doesn't specify time. Without time, Principal cannot be determined.

Statement III: Mentions a difference of ₹279 but doesn't specify time. Without time, Principal cannot be determined.

∴ The correct answer is Statement I alone is sufficient.

Alternate Method

Given: Three statements to find Principal (P).

Formula Used: CI = P[(1 + r/100)n − 1]; SI = (P×R×T)/100; Amount = P(1 + r/n)nt

Analysis:

Statement I:

⇒ CI = P[(1 + 25/100)2 − 1] = P[(5/4)2 − 1] = P(25/16 − 1) = 9P/16

⇒ SI = (P × 5 × 1) / 100 = P/20

⇒ 9P/16 − P/20 = 250 ⇒ (45P − 4P)/80 = 250 ⇒ 41P/80 = 250. P can be calculated.

Statement II:

⇒ It mentions interest rate 3.5% but the duration (years) is unknown. Equation: P(1.035)t = 3P + 2. Two unknowns (P and t), cannot solve.

Statement III:

⇒ It mentions rate 8% but the duration (years) is unknown. Amount difference requires 't' to determine P.

∴ The correct answer is The data in statement I alone is sufficient to answer the question, while the data in statement II and statement III alone are not sufficient to answer the question.

Additional Information

Data Sufficiency in Finance

To find a Principal amount in CI/SI problems, you must have values for Rate, Time, and a monetary value (Interest, Amount, or Difference).

Effective Rate Method

Effective CI Rate for 2 years = x + y + (xy/100). This helps compare CI and SI quickly as a percentage of the Principal.

Compounding Frequency

Semi-annual compounding: New Rate = R/2, New Time = 2 × T. Without knowing T, the impact of compounding cannot be calculated.

Question 145

Directions: The following question is accompanied by three statements (I), (II), and (III). You have to determine which statements(s) is/are sufficient/necessary to answer the questions.

A person marks the price of an article as Rs. y. What is the cost price of the article?

Statement I: The marked price of the article is 80% more than its cost price and the person sells it at 2x% discount. 

Statement II: The person gains 8% if he sells the article at x% discount and difference between Mark price and Selling price is 5y.

Statement III: The person loses 12% on selling the article at a discount of Rs. 217.

  1. AOption (a)

    The data in statement I and statement II are sufficient to answer the question, while the data in statement III alone is not sufficient to answer the question.

  2. BOption (b)

    The data in statement II alone is sufficient to answer the question, while the data in statement I and III is not sufficient to answer the question.

  3. COption (c)

    The data in statement I alone or in statement II alone or in statement III alone is sufficient to answer the question.

  4. DOption (d)

    The data in all the statements I, II and III is not sufficient to answer the question.

  5. EOption (e)

    The data in statements I and statement III are sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question.

View answer & explanation

Correct answer

Answer: (d)D.

The data in all the statements I, II and III is not sufficient to answer the question.

Why this answer is correct

Shortcut Trick To find the Cost Price (CP) numerically, we need a specific rupee value from the statements. Statement I & II only provide percentages (80%, 2x%, 8%, x%) and a relationship to y, where the discount 5y is mathematically impossible if MP = y. Statement III provides a real value (Rs. 217) and a loss %, but we don't know the Marked Price or x to link it back to the first two statements. Since the mathematical constraints in Statement II are contradictory (Discount > MP) and no combination provides a solvable system for CP, the data is insufficient. ∴ The correct answer is Data in all the statements I, II and III is not sufficient. Alternate Method

Given: MP = Rs. y From Statement I: ⇒ MP = 1.8 × CP ⇒ y = 1.8 × CP ⇒ CP = y/1.8 ⇒ Discount = 2x% of y. (Still in variables x and y) From Statement II: ⇒ Gain = 8% if Discount = x%. Also, Discount (MP − SP) = 5y. ⇒ CRITICAL ERROR: If MP = y, the discount cannot be 5y (Discount cannot exceed the price of the article). From Statement III: ⇒ Loss = 12% on selling at Rs. 217 discount. ⇒ 0.88 × CP = MP − 217 ⇒ 0.88 × CP = y − 217. ⇒ Combining with Statement I (y = 1.8 × CP): 0.88 × CP = 1.8 × CP − 217. ⇒ 0.92 × CP = 217 ⇒ CP = 235.86. However, Statement II provides conflicting data regarding x and y, making the entire dataset unreliable and insufficient for a definitive answer. ∴ The correct answer is ₹0. Additional Information Data Sufficiency Rules A question is only solvable if the statements provide consistent, non-contradictory information that reduces the number of variables to zero. Markup and Discount Formula Relation between CP and MP: MP/CP = (100 + Profit%)/(100 − Discount%). This requires specific numerical percentages to find the ratio. Logical Consistency In any trade transaction, Discount ≤ Marked Price. If a statement implies Discount > MP, the data is mathematically invalid.

Question 146

View answer & explanation

Correct answer

Answer: (a)A.

22

Why this answer is correct

Shortcut Trick

Total students = 550. Male (40%) = 220. Female (60%) = 330.

Male dancers = 10% of 220 = 22. Female dancers = 1/3 of 330 = 110.

Total dancers = 22 + 110 = 132.

Anchoring = 1/6 of 132 = 22.

∴ The correct answer is 22 students.

Alternate Method

Given: Total attendees = 550. Male = 40%. Female = 100% − 40% = 60%.

Formula Used: Number = Total × Percentage; Fraction equivalent (33.33% = 1/3; 16.67% = 1/6).

⇒ Number of Male students = 550 × 0.40 = 220.

⇒ Number of Female students = 550 − 220 = 330.

⇒ Males in dancing = 220 × 10% = 22.

⇒ Females in dancing = 330 × (1/3) = 110.

⇒ Total students in dancing = 22 + 110 = 132.

⇒ Students in anchoring = 132 × 16.67% = 132 × (1/6) = 22.

∴ The correct answer is 22 students.

Additional Information

Percentage to Fraction Conversion

Common exam fractions: 33.33% = 1/3, 16.67% = 1/6, 11.11% = 1/9, and 12.5% = 1/8.

Base Value Identification

Always identify the correct base for the percentage; here, anchoring is based on the dancing group, not the total student count.

Question 147

The difference between the age of father and mother is 3 years as father is elder than mother. They married after 3 years and after some time a child is born. The average age of the couple at the time of their son's birth is 35 years. Find the time after which the child is born if the initial age of the father before marriage was 29 years.

  4. DOption (d)

    3 years

  5. EOption (e)

    2 years

View answer & explanation

Correct answer

Answer: (a)A.

4 years 6 months

Why this answer is correct

Shortcut Trick

Total age of father and mother at birth = 35 × 2 = 70 years.

Initial age sum (before marriage) = 29 (Father) + 26 (Mother) = 55 years.

Total years passed for both = 70 − 55 = 15 years.

Years passed per person = 15 ÷ 2 = 7.5 years.

Time after marriage = 7.5 − 3 = 4.5 years.

∴ The correct answer is 4 years 6 months.

Alternate Method

Given: Initial age of father = 29 years; Difference = 3 years; Marriage after 3 years; Average age at birth = 35 years.

⇒ Initial Age of Mother = 29 − 3 = 26 years.

⇒ Age of Father at marriage = 29 + 3 = 32 years.

⇒ Age of Mother at marriage = 26 + 3 = 29 years.

⇒ Let child be born after t years of marriage.

⇒ Sum of ages at birth = (32 + t) + (29 + t) = 35 × 2

⇒ 61 + 2t = 70

⇒ 2t = 9

⇒ t = 4.5 years = 4 years 6 months.

∴ The correct answer is 4 years 6 months.

Additional Information

Average Age Concept

The sum of ages is calculated by multiplying the average age by the number of persons (Sum = Avg × n).

Age Gap Property

The difference between the ages of two people remains constant regardless of the number of years passed.

Time Progression

If x years pass, the age of every individual in a group increases by x, and the total sum increases by n × x.

Direction: Study the direction and answer the following questions.

Train Shatabadi Express of length 180 meters can cross a tree in 12 seconds. Another train August express of length 240 meters crosses the tree at the same time as the train Shatabadi. Both the trains entered a bridge of length 270 meters at the same time moving in opposite directions.

Question 148

Find out the train which will cross the bridge first and when it crosses the bridge completely then what will be the distance that the other train needs to covers to cross the bridge?

  1. AOption (a)

    Shatabadi, 50 m

  2. BOption (b)

    August, 53 m

  3. COption (c)

    August, 67.5 m

  4. DOption (d)

    Shatabadi, 67.5 m

  5. EOption (e)

    August, 52 m

View answer & explanation

Correct answer

Answer: (c)C.

August, 67.5 m

Why this answer is correct

Given:

Length of train Shatabadi express = 180 m

Length of train August express = 240 m

Time Shatabadi express takes to cross a tree = 12 sec

Time August express takes to cross a tree = 12 sec

Length of the Bridge = 270 m

Calculation:

Speed of Shatabadi express = 180/12 = 15 m/sec

Speed of August express = 240/12 = 20 m/sec

⇒ Time Shatabadi express takes to cross the bridge = (270 + 180)/15 = 30 sec

⇒ Time August express takes to cross the bridge = (240 + 270)/20 = 25.5 sec

Thus August express will cross the bridge first

The distance that Shatabadi need to cover

Distance covered by train Shatabadi in 25.5 sec = 25.5 × 15 = 382.5

Total distance = 270 + 180 = 450

⇒ Required distance = 450 – 382.5 = 67.5

∴ The distance Shatabadi express will cover after August express passed the bridge is 67.5 m.

View answer & explanation

Correct answer

Answer: (d)D.

36.5 sec

Why this answer is correct

Given:

Length of train Shatabadi express = 180 m

Time Shatabadi express takes to cross a tree = 12 sec

Length of the platform = 0.55 km

Formula used:

Speed = Distance/Time

Calculation:

Speed of Shatabadi express = 180/12 = 15 m/sec

Increased speed of Shatabadi express = 15 × (4/3) = 20 m/sec

Length of the platform in meters = 0.55 × 1000 = 550 m

Time = (550 + 180)/20 = 730/20 = 36.5 sec

∴ The time taken by the Shatabadi train to cover a platform is 36.5 sec.

Question 150

Shatabadi train started from city P at 11:00 am and traveled towards city R and after two hours, August started at R and traveled towards P. If the two trains met at 7:00 pm find the time taken by Shatabadi to reach city R after the two trains met each other.

View answer & explanation

Correct answer

Answer: (b)B.

8 h

Why this answer is correct

Given:

Length of train Shatabadi express = 180 m

Length of train August express = 240 m

Time Shatabadi express takes to cross a tree = 12 sec

Time August express takes to cross a tree = 12 sec

Formula used:

Speed = Distance/Time

Calculation:

Speed of Shatabadi express = 180/12 = 15 m/sec  = 15 × (18/5) = 54 km/h

Speed of August express = 240/12 = 20 m/sec = 20 × (18/5) = 72 km/h

Total time Shatabati express takes to reach the meeting point = 8 hours

Distance covered by Shatabadi express in 8 h = 54 × 8 = 432 km

Distance covered by August express in (8 – 2) hr = 72 × 6 = 432 km

As the distance covered by both the trains are same = 432 km

Shatabadi express will take 8 h to reach point R after the meeting.

∴ The time the Shatabadi train takes to reach the point R is 8 hours.

Question 151

View answer & explanation

Correct answer

Answer: (a)A.

24.7

Why this answer is correct

Given:

Length of train Shatabadi express = 180 m

Length of train August express = 240 m

Time Shatabadi express takes to cross a tree = 12 sec

Time August express takes to cross a tree = 12 sec

Formula used:

Speed = Distance/Time

Calculation:

We know that

 66.67% = (2/3)  

New time Shatabadi express takes to cross a tree = 12 × [(2 + 3)/3] = 20 sec

New time August express takes to cross a tree = 12 × [(100 + 150)/100] = 30 sec

⇒ New speed of Shatabadi express = 180/20 = 9 m/sec

⇒ New speed of August express = 240/30 = 8 m/sec

Required time = (180 + 240)/(9 + 8) = 420/17 = 24.7 sec

∴ Time taken by the two trains to cross each other is 24.7 sec

View answer & explanation

Correct answer

Answer: (b)B.

0

Why this answer is correct

Given:

Length of Shatabdi Express = 180 meters

Time taken by Shatabdi Express to cross a tree = 12 seconds

Length of August Express = 240 meters

Time taken by August Express to cross the same tree = 12 seconds

Formula Used:

Speed = Distance/Time

Calculation:

Normal speed of Shatabdi Express (S) = 180/12 = 15 m/s

Similarly, Normal speed of August Express (A) = 240/12 = 20 m/s

Hence we obtain:

4S – 3A = (4 × 15) – (3 × 20) = 0 

∴ The required value of (4S – 3A) is 0

A student goes shopping by bicycle and travels the distance of 10 km to reach the shop in 50 minutes. He buys a cylinder whose volume of 4620 m3 and also buys a cone. The volume of the cone is (1/7) times the volume of a cylinder and the height of the cone is 10 m. During returning from the shop he takes 10 minutes less time than coming to shop.

  5. EOption (e)

    1 km/hr

View answer & explanation

Correct answer

Answer: (a)A.

3 km/hr

Why this answer is correct

Given:

The distance is travelled by him = 10 km

Reaching time = 50 minutes

⇒ (5/6) hours

The volume of a cylinder = 4620 m3

The volume of a cone = (1/7) × the volume of a cylinder

And the height of a cone = 10 m

Reduce time = (50 - 10)

⇒ 40 minutes

⇒ 40/60 hours

⇒ 2/3 hours 

Formula used:

Speed = (Distance/Time)

The volume of cylinder = πr2h

The curved surface area of a cylinder = 2πrh, where r is the radius of a cylinder and h is the height of a cylinder.

The volume of a cone = (1/3)πR2H, where R is the radius of a cone, H is the height of a cone and π is 22/7

The slant height of a cone = √(height2 + radius2)

Calculation:

The speed when he went shopping = [(10)/(5/6)]

⇒ 12 km/hr

And the speed during returning = [(10)/(2/3)]

⇒ 15 km/hr

Increased speed = 15 - 12

⇒ 3 km/hr

∴ His increased speed was 3 km/hr

  5. EOption (e)

    √(170) m

View answer & explanation

Correct answer

Answer: (a)A.

√(163) m

Why this answer is correct

Given:

The distance is travelled by him = 10 km

Reaching time = 50 minutes

⇒ (5/6) hours

The volume of a cylinder = 4620 m3

The volume of a cone = (1/7) × the volume of a cylinder

And the height of a cone = 10 m

Reduce time = (50 - 10)

⇒ 40 minutes

⇒ 40/60 hours

⇒ 2/3 hours 

Formula used:

Speed = (Distance/Time)

The volume of cylinder = πr2h

The curved surface area of a cylinder = 2πrh, where r is the radius of a cylinder and h is the height of a cylinder.

The volume of a cone = (1/3)πR2H, where R is the radius of a cone, H is the height of a cone and π is 22/7

The slant height of a cone = √(height2 + radius2)

Calculation:

The volume of a cone = (1/7) × 4620

⇒ 660 m3

The volume of a cone = (1/3)πR2 × 10

⇒ 660 = (10/3) × (22/7) × R2

⇒ R2 = (660 × 3 × 7)/(10 × 22)   

⇒ R2 = 3 × 3 × 7

⇒ R = √(3 × 3 × 7)

⇒ R = 3√7 m

The slant height of cone = √[(10)2 + (3√7)2] 

⇒ √[100 + 63]  

⇒ √(163) m

∴ The slant height of a cone is √(163) m.

View answer & explanation

Correct answer

Answer: (c)C.

1320 m2

Why this answer is correct

Given:

The distance is travelled by him = 10 km

Reaching time = 50 minutes

⇒ (5/6) hours

The volume of a cylinder = 4620 m3

And the height of a cylinder = 30 m 

The volume of a cone = (1/7) × the volume of a cylinder

And the height of a cone = 10 m

Reduce time = (50 - 10)

⇒ 40 minutes

⇒ 40/60 hours

⇒ 2/3 hours 

Formula used:

Speed = (Distance/Time)

The volume of cylinder = πr2h

The curved surface area of a cylinder = 2πrh, where r is the radius of a cylinder and h is the height of a cylinder.

The volume of a cone = (1/3)πR2H, where R is the radius of a cone, H is the height of a cone and π is 22/7

The slant height of a cone = √(height2 + radius2)

Calculation:

The volume of cylinder = (22/7) × r2 ×  30

⇒ 4620 = (22/7) × r2 ×  30

⇒ r2 = (4620 × 7)/(30 × 22)

⇒ r2 = 49

⇒ r = √(49)

⇒ r = 7 m

The curved surface area of a cylinder = 2 × (22/7) × 7 × 30

⇒ 1320 m2

∴ The curved surface area of a cylinde is 1320 m2
