Arithmetic Reasoning

Q1: In a caravan, in addition to 50 hens, there are 45 goats and 8 camels with some keepers. If the total number of feet be 224 more than the number of heads in the caravan, the number of keepers is

A 5

B 8

C 10

D 15

ANS:D - 15

Explanation: Let number of keepers be x. Then, Total number of feet = 2 x 50 + 4 x 45 + 4 x 8 + 2x = 2x + 312. Total number of heads = 50 + 45 + 8 + x= 103 + x. Therefore (2x + 312) = (103 + x) + 224 or x = 15.
