The notion that ancient hunter-gatherers lived in a perfect and peaceful world is beguiling but wrong. If life expectancy is any measure of progress, then the current figure for the developed world - 78 years - is clearly far greater than that for either hunter- gatherers or farmers in the ancient world.

Gurmeet Kaur answered • 4 hours ago

Solution: Option 1 does not affect the conclusion at all, since it does not pertain to the comparison between modern developed societies and ancient hunter-gatherers.

Similarly, option 2 is also a non sequitur, as ancient farmers do not factor into the conclusion.

While option 3 does suggest that progress (in the technological sense) positively correlates to life expectancy, the lack of explicit comparison to either modern developed societies or ancient hunter-gatherers makes it an unsuitable answer.

Option 4 shows that the life of ancient hunter-gatherers was not perfect or peaceful, and that their actual lifespan was even shorter than their ‘natural’ lifespan (i.e. they died unnatural deaths). So it strengthens the conclusion.

Hence, the correct answer is option 4.

Reve Schiller is a corporate turnaround artist, and having previously steered Jordan Steel and Pan Asia Airlines through bankruptcy, he is now attempting to do the same with Upsilon Corp, the nation's largest supplier of auto parts. It's shaping up as a bumpy ride. Days after Upsilon filed for bankruptcy protection on August 8, he was criticized for providing a generous severance package for the senior management while indicating that he planned to ask for steep cuts in pay and benefits from the company's more than 68,000 unionized workers.

Upsilon's move puts the retirement pensions of its 60,000 U.S. employees and 19,000 retirees at risk and worsens the eroding position of its chief customer, Union Motors, which announced a 2.3 billion dollar third quarter loss recently. UM is contractually obligated to pay thousands of Upsilon workers a portion of any benefits they might lose in bankruptcy, a bill that could run as high as 13 billion dollars. One immediate reason for Upsilon's filing was to forestall a 1.8 billion dollar payment it was required to make to its pension programs in January. Schiller blames the defined pension benefit, which he calls an "anachronism," for his company's downfall and points to the downward wage pressure exerted by globalization for precipitating the current crisis.

Gurdevi answered • 4 hours ago

Solution: The passage states that despite the company's financial woes, the senior management received large severance packages, while steep cuts were announced for the labor workforce. Thus, it would only be fair that the lowering of increments and pay cuts be evenly distributed throughout the organization. The correct decision would therefore be to participate in the agitation.

Options 2, 4 and 5 would be very passive actions to undertake.

The rate (per month) of increase in income is twice that of the expenditure. If there is no saving in the first month and the total savings in the first two months is one-fifth of the initial income, then the rate at which the expenditure increased is

- a)10%
- b)20%
- c)25%
- d)15%

Correct answer is option 'B'. Can you explain this answer?

Suresh Rani answered • 4 hours ago

Let the initial income and expenditure be / and E respectively.

Income in the second month = /(1 + 0.02r) and expenditure in the second month = E( 1 + 0.01 r); where ris the rate of increase in the expenditure.

Total savings at the end of two months = ( / - E ) + [(/ + 0.02Ir) - (E + 0.01 Er)

Income in the second month = /(1 + 0.02r) and expenditure in the second month = E( 1 + 0.01 r); where ris the rate of increase in the expenditure.

Total savings at the end of two months = ( / - E ) + [(/ + 0.02Ir) - (E + 0.01 Er)

= 2(1- E) + r(0.02/- 0.01E)

= 2(1- E) + r(0.01 / - 0.01 E + 0.01 /)

= (2 + 0.01 r)(/ - E) + 0.01/r

Since the savings in the first month is 0, / - E = 0

0.01/r= 0.2/

0.01r=0.2

r = 20%

Hence, option 2.

Answer the following question based on the information given below.

This is my modest proposal: Google should create Google Kids, a search engine that filters the Web for children. Think back to when you were a kid and your parents dropped you off at the library. In the children’s section, there was no ‘inappropriate’ stuff to be found. Similarly, Google Kids would be a sort of children’s section of the Web, focused on providing high-quality results based on age.

What is the basic assumption of the author’s argument?

Neelam Devi answered • 4 hours ago

Solution: Option 2 is far too negative, and the issue of trusting children has no basis in the paragraph.

It is unlikely that the author is making this proposal directly to Google. Also “keenly” is not necessary in the assumption. Eliminate option 3.

The library is mentioned only as an example of how to provide an appropriate section for kids - equating library with physically searching for information and google with reading books is stretching the given data. Eliminate option 4.

Option 5 is not an assumption - it is the point of the library example.

Only option 1 is a basic assumption - a special search engine for kids is necessary only if the regular one provides results that are unsuitable for children.

Hence, the correct answer is option 1.

Balvinder Kaur answered • 4 hours ago

Part D must be the first since it introduces the idea that is carried forward through the rest of the sentence. Also, it begins with the relative pronoun “that”.

Then part C must follow D since it names the two subjects that are spoken of in part D.

The part that follows C must define it, hence, only part A can follow.

A is in turn followed by B which maintains the flow of the sentence.

Thus, the correct order is DCAB.

Hence, the correct answer is option 2.

A cask was full of wine. A person used to draw out 25% of the wine from the cask and replace it with water. He repeated the same process 3 times and thus there was only 135 litres of wine left in the cask and the rest of the jar was filled with water. What was the initial amount of wine in the cask?

- a)265 litres
- b)280 litres
- c)300 litres
- d)320 litres

Correct answer is option 'D'. Can you explain this answer?

Saroj answered • 4 hours ago

Let the initial amount of wine in the cask be W, then

135 = W(1 - 25 / 100)^{3}

135 = W(3 / 4)^{3}

W = 135 x 64 / 27

W= 320 litres

The initial amount of wine in the cask is 320 litre.

Hence, option 4.

135 = W(1 - 25 / 100)

135 = W(3 / 4)

W = 135 x 64 / 27

W= 320 litres

The initial amount of wine in the cask is 320 litre.

Hence, option 4.

There have been many instances of attacks on senior citizens in Mumbai. There have been 4 cases of such attacks in the JBR society in Mumbai, which is located on the Gaurya road. Rajshri More (65) and Rani Gala (61) became victims of chain- snatchers.The two incidents took place within a span of one hour. Around 12.30 pm, two unidentified bikers snatched More's chain on Gaurya Road. Similarly, two unidentified men on a motorcycle snatched Gala's chain near JBR society around 1.30 pm. Gala suffered severe injuries to her head as she tried to resist the attackers. "The boys were well-dressed and looked very sophisticated," said Gala, later on, from the hospital bed. Mr. Kale, the inspector in charge of that area of Mumbai is in a dilemma as to how to prevent or even stop such attacks, as he is short of people in his team.

Mamta Devi answered • 4 hours ago

Solution: Option 2 is a very defeatist attitude for a policeman. The passage mentions that Mr. Kale wants to take some action in order to prevent these attacks. Therefore, running away will not be an option. So, option 2 can be ruled out.

Arguing will not solve the problem and will only result in the transfer of Mr. Kale. Therefore, option 3 can also be eliminated.

Simply mobilizing the youth without taking any legal action will not help stop these attacks. The civilians have to be guided and supported by trained officers. Eliminate option 4.

Waiting for more men in his team might take a long time.

And if the higher authorities do not know Mr. Kale's problem of having very few men in his team, they won't address it.

He will first have to make the authorities aware of this problem. Therefore, option 5 can be eliminated.

Option 1 is what Mr. Kale should follow. By prioritizing the issue, he is ensuring that his men concentrate on the situation at hand first.

Hence, the correct answer is option 1.

Shanti Devi answered • 4 hours ago

Solution: The decision to give large severance packages was taken by Schiller and approved by the board of directors. Despite the increasing pressure to reduce costs, the former senior management did not forfeit a part of their severance pay. Thus, Schiller, the Board of Directors and the former senior management are responsible. None of the other entities are responsible for the current financial dilemma.

Hence, the correct answer is option 3.

Let the length of the garden be l m and the breadth be b m.

Then it's area is lb m^2.

According to the problem, (l - 5)(b+3) =lb -9

=> 3l - 5b = 6 â€¦(1)

Also as per the problem, (l+3)(b+2) = lb + 67

= 2l + 3b = 61â€¦.(2)

Multiplying (1) by 3 and (2) by 5 and adding we get

19l = 323 = l = 17

Hence the length of the garden is 17 meters.

Correct answer is option 'B'. Can you explain this answer?

Talent Skill Learning answered • 13 hours ago

Assume that P does x units of work in one day.

Total work = 42x

One day work of Q = 1.26x units

One day work of R = 1.26x ï¿½ 1.5 = 1.89x units

Total work done by Q and R in one day = 1.26x + 1.89x = 3.15x

So, Q and R can finish the work in 42x/3.15x = 13 days approximately.

A tank has an inlet pipe and an outlet pipe. If the outlet pipe is closed, then the inlet pipe fills the empty tank in 8 hours. If the outlet pipe is open, then the inlet pipe fills the empty tank in 10 hours. If only the outlet pipe is open, then in how many hours the full tank becomes half-full?

From CAT 2017 â€“ Quantitative Aptitude â€“ Arithmetic â€“ Pipes and Cisterns, we can see that,

The time in which inlet pipe can fill tank (a) = 8 hrs

Time in which outlet pipe can empty the tank = b

1/a â€“ 1/b = 1/10

On solving, we get b = 40 hrs

Half of the tank will be empty when b=20 hrs

A tank is fitted with pipes, some filling it and the rest draining it. All filling pipes fill at the same rate, and all draining pipes drain at the same rate. The empty tank gets completely filled in 6 hours when 6 filling and 5 draining pipes are on, but this time becomes 60 hours when 5 filling and 6 draining pipes are on.

Suppose inlets of type A fill A liters per minute and type B fills B liters per minute.

So, capacity of tank = 30(10A + 45B) = 60(8A + 18B)

â‡’10A + 45B = 16A + 36B

â‡’6A = 9B

â‡’A = 1.5B

â‡’Capacity of Tank = 30(15B + 45B) = 30*60B = 1800 B

Time taken to fill the tank with 7A and 27B, which is 10.5B and 27B, which is 37.5B = 1800 B / 37.5 B = 48 minutes

Talent Skill Learning answered • 14 hours ago

let usual efficiency of A = 2a and that of B = b

So total work = 12*(2a+b) = 24a+12bâ€”â€”1)

In 2nd case when efficiency of A is halved and efficiency of B get tripled , new efficiency of A = 2a/2 = a

New efficiency of B = b*3 =3b

Total work = 9(a+3b) = 9a+27b â€”â€”2)

From eq 1) and 2)

24a+12b = 9a + 27b

15a = 15b

Or a=b

So total work = 24a+12b = 24a+12a = 36a

Time taken by A alone to complete the work = 36a/2a = 18 days

Let the capacity of the tank be 60 litres (LCM of 4, 10, 12 and 60).

Pipe A can fill or drain 60/4 or 15 litres in 1 minute.

Similarly, pipes B, C and D can fill or drain 6 litres, 5 litres and 3 litres in 1 minute respectively.

We want to fill the tank half, which is 30 litres, in 30 minutes. This is equal to 1 litre in 1 minute.

Correct answer is option 'A'. Can you explain this answer?

Bakliwal Institute answered • 14 hours ago

Ratio of time taken by A and B to complete the work alone = 1: 1.25 = 4x : 5x

As A complete half of the work alone and B complete 5% of the work alone, so they will complete remaining 45% of work in 4 days .

So time taken by them to complete the whole work together = 4 * 100/45 = 80/9

Or (4x*5x)/(4x+5x) = 80/9

x = 4

Thus time taken by B to complete the work alone = 5x = 20 days

A tank is connected with both inlet pipes and outlet pipes. Individually, an inlet pipe can fill the tank in 7 hours and an outlet pipe can empty it in 5 hours.

Let there be x inlet and y outlet pipes.

x + y = 11

Assume that the capacity of the tank is 35 units.

Inlet pipe fills 5 units and the outlet pipes empties 7 units in one hour.

The completely filled tank empties in 7 hours.

7y - 5x = 5

Solving two equations, y = 5 and x = 6

Target Study Academy answered • 14 hours ago

As per the question from CAT 2017 â€“ Quantitative Aptitude â€“ Arithmetic â€“ Time and Work, we can see that,

On Day 1, the person works alone. So, work done on Day 1 = 1/120

Next day, another person joins him, Work done on Day 2 = 2/120

And so on, until the final day

So, sum total of work done = 1/120 + 2/120 +â€¦â€¦â€¦+ n/120 = 1

(1/120) (1 + 2+3+â€¦â€¦+n) = 1

(1/120) [n(n+1)/2] = 1 (Sum of n positive integers)

On solving, we get n = 15.

Target Study Academy answered • 14 hours ago

Let pump A alone can fill the tank in t hours so time taken by pump B alone = t-2 hours

As per question , (t-3)/t+2/(t-2)=1

t^2-3t+6=t^2-2t

Or t=6

So the time at which pumps tank is emptied = 8 pm â€“ 6 hours = 2 pm

Time taken by both pumps together to fill the tank =(6ï¿½4)/(6+4)=2.4 hours=2 hour 24 minutes

Thus tank will be filled by 2 pm + 2 hour 24 minutes=4:24 pm

Many firms fail because when they begin exporting, they have not researched the target markets or have not developed an international marketing plan to be successful. A firm must clearly define goals objectives and potential problems. Secondly it must develop a definitive plan to accomplish it's objective regardless of problems involved. Unless the firm is fortunate enough to possess a staff with considerable expertise, it may not be able to take this crucial first step without qualified outside guidance.

Often top management is not committed enough to overcome the initial difficulties and financial requirements of exporting. It can often take more time and effort to establish a firm in a foreign market than in domestic one. Although the early delays and costs involved in exporting may seem difficult to justify when compared to established domestic trade the exporter should take a more objective view of this process and carefully monitor international marketing efforts through these early difficulties. If a good foundation is laid for export business the benefits derived should eventually out-weigh the investment.

Another problem area is in the selection of foreign distributor. The complications involved in overseas communications and transportation require international distributors to act with greater independence than their domestic counterparts also since a new exporter's trademarks and reputation is usually unknown in the foreign market. Foreign customers may buy on the strength of distributing agent's reputation. A firm should therefore conduct a thorough evaluation of the distributor's facilities, the personnel handling its account and managements methods employed.

Another common difficultly for new exporter is the neglect of the export market once the domestic one booms: too many companies only concentrate on exporting when there is recession. Others may refuse to modify products to meet the regulations or cultural preferences of other countries. Local safety regulations cannot be ignored by exporters. If necessary modifications are not made at the factory the distributor must make them, this is usually at a greater cost and probably not as satisfactory as it should be. It should also be noted that the resulting smaller profit margin makes the account less attractive.

If exporters expect distributing agents to actively promote their accounts they must be trained and their performance must be continually monitored. This requires a company's marketing executive to be located permanently in the distributor's geographical areas until there is sufficient business to support the representative. The distributor should also be treated on an equal basis with domestic counterparts for e.g. special discount offers, sales incentive programmes and special credit terms should be available.

Considering a joint venture or licensing agreement is another option for new exporters. However, many companies still dismiss international marketing as unviable. There are a number of reasons for this. There may be import restrictions in the target market. The company may lack sufficient financial resources or its product line may be too limited. Yet many products that can compete on a national basis can be successful in the majority of world markets. In general, all that is needed for success is flexibility in using the proper combinations of marketing techniques.

Group Question

Answer the questions based on the passage given below.

The US Treasury Department recently announced that it would start demanding details of the shell companies that rich foreigners use to buy real estate in Manhattan and Miami-Dade County. This is a good step that should help law enforcement agencies crack down on money laundering, tax evasion and other crimes. The program should be broadened to cover the whole country, and must be forcefully carried out.

In recent years, there have been certain sections of people that have stashed billions of dollars of wealth in the United States by buying property and other costly assets. These purchases are generally made through limited liability corporations that are not required to disclose their wealthy owners or beneficiaries. While limited liability corporations have many legitimate purposes, there is no justification for allowing owners to shield their identities even from law enforcement and regulators. The secrecy is so complete that law enforcement officials say they are often unable to identify the true owners. All efforts by lawmakers have been thwarted by lobbying from the financial and real estate industries and state governments.

All efforts by lawmakers have been thwarted by lobbying from the financial and real estate industries and state governments.

The department currently requires mortgage lenders to know the identities of the true owners of shell companies in transactions that involve loans. Under the new policy, the department’s Financial Crimes Enforcement Network will require details of limited liability companies that buy properties without loans. However, the order applies only to Manhattan and Miami-Dade County, and will be effective for only 180 days, starting in March.

The department should also adopt pending regulations that would require financial firms to know who owns the limited liability companies whose accounts they manage. It is absurd that regulators would not require such basic transparency as a matter of course. The current system practically lays out the welcome mat for some foreigners hiding assets from their governments, making United States one of the world’s biggest tax havens.

Supporters of the current system may argue that requiring more transparency would burden financial institutions without ending money laundering and tax evasion, since determined criminals will find ways to thwart the law. But that doesn’t justify doing nothing about this hole in financial regulations.
