Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 42.
The ratio of marks of Rohan in English, Science, and mathematics = 2 : 1 : 3.
Let the marks of Rohan in English, science, and mathematics be 2x, x and 3x
According to the question,
⇒ 1x + 2x + 3x = 126
⇒ 6x = 126
⇒ x = 21
So, marks in English = 21 × 2 = 42
