The first boy, whose home is 5 km away from the school walks at a speed of 5 km/hr and the second boy whose home is 8 km away from the school walks at a speed of 6 km/hr. If their homes are in directly opposite directions, what will be the distance between the two boys at 2:10 pm?

Detailed Solution for UPSC CSE Prelims Paper 2 Practice Test - 10 - Question 1

UPSC CSE Prelims Paper 2 Practice Test - 10 - Question 20

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

The whole biosphere, like the individual organisms that live inside it, exists in a chemically dynamic state. In this homeostatic system, a great number of organic compounds are synthesized, transformed, and decomposed continuously; together, these processes constitute the major parts of the carbon cycle. For the smooth operation of this cycle, degradation is just as important as synthesis: the green plants produce great quantities of polymers, such as cellulose, and innumerable other compounds like alkaloids, terpenes, and flavonoids, that green plants cannot use as sources of energy during respiration. The release of the carbon in these compounds for recycling depends almost entirely on the action of both aerobic and anaerobic bacteria and certain types of fungi. Some bacteria and fungi possess the unique and extremely important biochemical asset of being able to catalyse the oxidation of numerous inert products, thereby initiating reaction sequences that produce carbon dioxide and so return much carbon to a form that actively enters into life cycles once again.

Q. The passage contains information that would answer which of the following questions about the carbon cycle?
1. What are some of the compounds that are broken down in the carbon cycle?
2. Why are some compounds that are involved in the carbon cycle less reactive than others? 3. What role do bacteria and fungi play in the carbon cycle?

Detailed Solution for UPSC CSE Prelims Paper 2 Practice Test - 10 - Question 20

In the passage it is information about the compounds that are broken down in the carbon cycle and the role bacteria and fungi play in the carbon cycle.

UPSC CSE Prelims Paper 2 Practice Test - 10 - Question 21

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

The whole biosphere, like the individual organisms that live inside it, exists in a chemically dynamic state. In this homeostatic system, a great number of organic compounds are synthesized, transformed, and decomposed continuously; together, these processes constitute the major parts of the carbon cycle. For the smooth operation of this cycle, degradation is just as important as synthesis: the green plants produce great quantities of polymers, such as cellulose, and innumerable other compounds like alkaloids, terpenes, and flavonoids, that green plants cannot use as sources of energy during respiration.

Some bacteria and fungi possess the unique and extremely important biochemical asset of being able to catalyse the oxidation of numerous inert products, thereby initiating reaction sequences that produce carbon dioxide and so return much carbon to a form that actively enters into life cycles once again.

Q. The author implies that which of the following is the primary reason that degradation is as important as synthesis to the smooth operation of the carbon cycle?

Detailed Solution for UPSC CSE Prelims Paper 2 Practice Test - 10 - Question 21

From the passage it can be inferred that that degradation is as important as synthesis to the smooth operation of the carbon cycle as decomposition permits the recycling of carbon that would otherwise be fixed in certain substances.

UPSC CSE Prelims Paper 2 Practice Test - 10 - Question 24

Directions 
A book is divided into 6 chapters. The following pie chart denotes the percentage of the total pages devoted to each chapter.

If Chapter 1 contains 60 pages, the number of pages in chapter 5 is?

Detailed Solution for UPSC CSE Prelims Paper 2 Practice Test - 10 - Question 24

Chapter 5 is 18%, whereas Chapter 1 is 4%.

UPSC CSE Prelims Paper 2 Practice Test - 10 - Question 29

The table represent the percentage expenditure of the income of A, B, C, D, E and F on different items.

If the amount of money spent on food by C and D are ₹72000 and ₹86400 respectively, then the annual income of C is what percentage of the annual income of D?

Detailed Solution for UPSC CSE Prelims Paper 2 Practice Test - 10 - Question 29

The correct option is C.
24% of total of C = 72000
Total of C = 72000*100/24 = 300000
18% of D = 86400
Total of D = 86400*100/18 =480000
Percentage of C with respect to D = 300000/480000*100 = 62.5%
