Question : Ram got twice as many marks in English as in Science. His total marks in English, Science, and Maths are 180. If the ratio of his marks in English and Maths is 2 : 3, what are his marks in Science?
Option 1: 30
Option 2: 60
Option 3: 72
Option 4: 90
Correct Answer: 30
Solution :
Given:
Ram got twice as many marks in English as in Science.
Let Ram's marks in Science = x
So, his marks in English = 2x
and his marks in Maths = 3x
According to the question,
x + 2x + 3x = 180
⇒ 6x = 180
$\therefore$ x = 30
Hence, the correct answer is 30.
