Answer 2

Question :- Sum of the ages of father and son is 68. After 8 years father will be thrice as old as son. The present age

(in years) of the son is :-

A) 18

B) 16

C) 15

D) 13

Answer :-

Let us assume that, Present age of son is x years.

so,

→ Father's age = (68 - x) years.

now,

→ After 8 years son will be = (x + 8) years old.

→ After 8 years father will be = (68 - x) + 8 = (76 - x) years old.

A/q,

→ Father = 3 * son

→ (76 - x) = 3(x + 8)

→ 76 - x = 3x + 24

→ 76 - 24 = 3x + x

→ 4x = 52

→ x = 13 years. (D) (Ans.)
