UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 18 (May 30, 2021) - Question 4

Direction: The following graph represents a company ‘A’ and a market ‘B’. The company has four warehouses namely P, Q, R and S which are in midway between the company and the market. The number adjacent to the arrow represents the cost of transportation (in thousands) of one truck along the path.

Q. Which warehouse(s) should the company use the most to have minimum transportation cost?

Detailed Solution for UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 18 (May 30, 2021) - Question 4

Different possible routes are:
APB → Cost = 10 + 6 = 16 thousand
APQRB→ cost = 10 + 3 + 3 + 3 =19 thousand
AQRB → Cost = 3 + 3 + 3 = 9 thousand
ASRB→ Cost = 8 + 3 + 3 =14 thousand
ASB→ Cost = 8 + 7 = 15 thousand
The path A→ Q→ R → B gives minimum transportation cost.
So, the company can use the warehouses Q and R to minimize the transportation costs.
Hence, option (d) is the correct answer.

UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 18 (May 30, 2021) - Question 5

Direction: The following graph represents a company ‘A’ and a market ‘B’. The company has four warehouses namely P, Q, R and S which are in midway between the company and the market. The number adjacent to the arrow represents the cost of transportation (in thousands) of one truck along the path.

Q. How many different routes are possible for the company to send goods from A to B if it is willing to use only those routes on which the transportation cost is not more than 50% higher than the cost along the cheapest route?

Detailed Solution for UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 18 (May 30, 2021) - Question 5

Different possible routes are:
APB→ Cost = 10 + 6 = 16 thousand
APQRB→ cost = 10 + 3 + 3 + 3 = 19 thousand
AQRB → Cost = 3 + 3 + 3 = 9 thousand
ASRB→ Cost = 8 + 3 + 3 =14 thousand
ASB→ Cost = 8 + 7 = 15 thousand
Minimum Cost of transportation = Rs. 9,000 along AQRB.
The company is looking for routes that are up to 50% costlier than the minimum cost route.
So, maximum acceptable cost of transportation = 9000 + 50% of 9000 = Rs. 13,500
No other routes have a transportation cost less than Rs. 13,500.
So, the company can use only one route.
Hence, option (a) is the correct answer.

UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 18 (May 30, 2021) - Question 9

There are three numbers whose product is 308700 and each of these three numbers is formed by 3 distinct prime numbers. Average of all three numbers is:

Detailed Solution for UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 18 (May 30, 2021) - Question 9

308700 = 2x 32 x 5x 73
= (2 x 3 x 7)×(2 x 5 x 7)×(3 x 5 x 7)
(combination of distinct prime numbers) = 42 x 70 x 105.
Therefore, the average of 42, 70 and 105 = 42+70+105/3 = 72.33.

UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 18 (May 30, 2021) - Question 10

UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 18 (May 30, 2021) - Question 12

Let x = average of the first five prime numbers of the number system and y = average of the first five composite numbers of the number system, then, the difference of x and y is:

Detailed Solution for UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 18 (May 30, 2021) - Question 12

The first 5 prime numbers of the number system are 2, 3, 5, 7 and 11.
The first 5 composite numbers of the number system are 4, 6, 8, 9 and 10.
So x = 2+3+5+7+11/5 = 28/5 and
y = 4+6+8+9+10/5 = 37/5
So, the required difference = y – x = 37/5 – 28/5  = 37–28/5 = 9/5=1.8

UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 18 (May 30, 2021) - Question 14

Statement — Government stop spending huge amounts of money on international sports.
Arguments —
1. Yes, this money can be utilised for upliftment of the poor.
2. No, sport persons will be frustrated and will not get international exposure.

Detailed Solution for UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 18 (May 30, 2021) - Question 14

Clearly, the spending of money on sports cannot be avoided merely because it can be spent upon our various other problems. Therefore, argument 1 is not valid. In case the expenses on sports are curtailed, the sport persons would face lack of facilities and training. Our country will lag behind in international sports competitions.

Q. A person takes 10 min to cover 1 km distance on a motorable road, 30 min to cover 1 km on the muddy path and 1 hour to cover 1 km in the jungle terrain. How long will he take to reach A from B?

Detailed Solution for UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 18 (May 30, 2021) - Question 16

Read the information given below carefully and answer the following question.

India has missed out fairly comprehensively on a large part of the lessons of Asian economic development, which has rapidly enhanced human well-being and capability along with- indeed as a part of- pursuing fast economic growth. A critical part of the East Asian strategy has been the use of public revenue, itself expanded by economic growth, to remove huge deficiencies in social, educational and health services, and to meet the growing demands of social and physical infrastructure, while making public services more accountable and efficiently organised. China’s experience also shows that devoting much more public revenue than India does to the education health care and nutrition of the people is compatible with- and can be very helpful for high and sustained growth. Comparing India’s miserable allocation of 1.2 percent of GDP to  public expenditure on health with China’s much higher figure of 2.7 per cent, what is strikingly is not only the lack of understanding of the demands of public health in India, but also how limited the understanding of many champions of economic growth are of the actual requirements for fast and sustained economic growth. We are bombarded by deafening rhetoric on ‘the priority of economic growth,’ with little thought given to health, education and other aspects of the formation of human capabilitiesreflecting a disarmingly foggy understanding of how long-run growth and participatory development can actually be achieved and sustained.

Q. The keynote that seems to be emerging from the passage is that

Detailed Solution for UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 18 (May 30, 2021) - Question 25

The passage discusses how deficiencies in enhancing human well-being and capability along with pursuing fast growth has affected long term growth and participatory development. Thus, option (b) is the correct answer which suggests India should invest in human capability formation.
Option (a) is incorrect as the passage does not suggest anything on India’s competition with China.
Option (c) is incorrect as the passages does not blame India’s pursuit of high economic growth as a reason for low resource development. Passage intends to point out the flawed understanding on development and how to achieve it.
Option (d) is incorrect as the passage does not discuss on India’s usage of human capabilities for generating growth.

UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 18 (May 30, 2021) - Question 29

The government is urged by some to refrain from increasing the deficit. While it is right to be concerned with the consequences, the correct approach would be to aim to balance the budget over the growth cycle. That is, the deficit may be increased as the economy slows and contracted as the economy quickens. To object to an increase in the deficit irrespective of the state of the economy is to be dogmatic. Since 2014 the government has focussed aggressively on the supply side by making it easier for private firms to produce. But we are now facing a demand shortage in the economy. The immediate thing to do is to expand public investment in infrastructure.
Q.
The keynote that seems to be emerging from the passage is that

Detailed Solution for UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 18 (May 30, 2021) - Question 29

The passage discusses government’s approach to budget and emphasises that deficit can be increased during slowing of economy. Thus (b) is the correct option.
Option (a) is not correct as the passage mentions that the immediate thing is to expand public investment in infrastructure but does not tell that lack of public investment is the root cause of economic problems.
Option (c) is incorrect as the passage tells that India is facing a demand shortage but does not tell its impact on budget making process.
Option (d) is incorrect as passage specifically mentions that the deficit may be increased as economy slows down.
