A student scored 20% more marks in Math than in Science. If the average of his marks in both subjects is 66, what are his marks in Science?
Show answer & explanation
Correct answer: D
Explanation
Given:
Math marks = 20% more than Science
Average of both = 66
Total marks of both subjects = 66 × 2 = 132
Let Science marks = x
Math marks = 1.2x
x + 1.2x = 132
2.2x = 132
x = 60
