Question

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. 16
• B. 18
• C. 20
• D. 24

Answer 1

Answer:

C. 20

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