Question

A boy is 26 years younger than his father. In 3 years' time his age will be 1/3 his father's age. Find the boy's present age

Answer 1

10 years

Explanation:

let age of the boy x , and let age of his dad y

x - y = 26

y + 3 = (x+3) / 3

x - 26 = (x+3) / 3

3x - 69 = x + 3

2x = 72

x = 26, y = 10
