The ratio of the ages of father and son at present is 6 : 1. After 5 years ratio will become 7 : 2. The present age of the son is?

5 years
6 years
9 years
10 years

Correct Answer: 5 years

Explanation:

Let the ages of father and son be 6x and x respectively.
From question, (6x + 5) / (x + 5) = 7 / 2
⇒ 2(6x + 5) = 7(x + 5)
⇒ (12 - 7) x = 35 - 10
⇒ x = 5
∴ Son's present age = 5 years
