Question from UPSC Prelims 2020 CSAT Paper

Explanation : 

Average score of batsman calculation

After his 50th innings, the batsman’s total score was (50 * 46.4) = 2320.

After his 60th innings, his average score increased to (46.4 + 2.6) = 49. So his total score after 60 innings was (60 * 49) = 2940.

The difference between these two totals is the total score he made in his last ten innings: (2940 – 2320) = 620.

So his average score in those last ten innings was (620 / 10) = 62.

Q. The last end of the state is not to dominate men, nor to restrain them by fear; rather it is so to free each man from fear that he may live and act with full security and without injury to himself or his neighbour. The end of the state, I repeat, is not to make rational beings into brute beasts and machines. It is to enable their bodies and their minds to function safely. It is to lead men to live by, and to exercise, a free reason; that they may not waste their strength in hatred, anger and guile, nor act unfairly toward one another.
