Answer 1

Given:

Man's age = 4 × Son's age.

After 6 years, Man's age = 3 × Son's age.

Calculation:

Let the son's present age be x, then the man's present age becomes 4x.

According to the question,

After 6 years

4x + 6 = 3(x + 6)

⇒ 4x - 3x = 18 - 6

⇒ x = 12

Son's age = x = 12 years

And, Man's age = 4x = 48 years

Hence, The sum of their present ages is 12 + 48 = 60 years.
