Question

A man is now 3times as old as his son.In 10 years time, the sum of their ages will be 76 .How old was the man when his son was born?

Answer 1

let son's present age = x

man 's present age = 3 x

A.T.Q

x+10+3x+10=76

4x+20=76

4x=76-20

4x=56

x=56/4

x=14

son's present age =14

man's present age= 3*14=42

man's age when his son was born =42-14=28 years
