The sum of the present ages of a father and his son is 60 years . Six years ago, father's age was five times the age of the son. After 6 years, son's age will be -

A 12 years
B 14 years
C 18 years
D 20 years

Correct Answer: 20 years

Let the present ages of son and father be x and (60 - x) years respectively. Then, (60 - x) - 6 = 5(x - 6) ⇒ 54 - x = 5x - 30 ⇒ 6x = 84 ⇒ x = 14 ∴ Son's age after 6 years = (x + 6) = 20 years.
