Question 65: Basic Numeracy
Four persons, Alok, Bhupesh, Chander and Dinesh have a total of ₹ 100 among themselves. Alok and Bhupesh between them have as much money as Chander and Dinesh between them, but Alok has more money than Bhupesh; and Chander has only half the money that Dinesh has. Alok has in fact ₹ 5 more than Dinesh has. Who has the maximum amount of money ?
AnswerUPSC’s answer is (a).
The total is 100. Alok + Bhupesh = Chander + Dinesh, so each pair has 50. Chander has half of Dinesh's money, so Dinesh has two thirds of 50, about 33.33, and Chander about 16.67. Alok has 5 more than Dinesh, about 38.33, so Bhupesh has 50 - 38.33, about 11.67. The largest amount is Alok's.
Why each option is right or wrong
- (a) Right. Alok has about 38.33, the most.
- (b) Bhupesh has the least, about 11.67.
- (c) Chander has about 16.67.
- (d) Dinesh has about 33.33, less than Alok.
