Question

Sushil got thrice as many marks in English as in Science. His total marks in English, Science and Maths are 162. If the ratio of his marks in English and Maths is 3 : 5, find his marks in Science.

Options:

A . 12

B . 18

C . 24

D . 30

Answer: Option B
Given,
Number of marks obtained by Sushil in English = 3x
Number of marks obtained by Sushil in Science = x
Number of marks obtained by Sushil in Mathematics = 5x
Total number of marks obtained by Sushil = 3x + x + 5x = 162

Therefore, 3x + x + 5x = 162
⇒ 9x = 162
⇒ x = 162/9
⇒ x = 18

Therefore, number of marks obtained by Sushil in Science = 18.

Hence, Option B (18) is the correct answer.
