Aman age is three times more than his sons age. Ten years ago he was five time his son age. What are present ages

Son's age = 20 years

Father's age = 60 years

Step-by-step explanation:

Let son's age be x

Fathers age = 3x

Ten years ago:

Sons age = x - 10

Fathers age = 3x - 10

3x - 10 = 5 * (x-10)

3x - 10 = 5x - 50

50 - 10 = 5x - 3x

40 = 2x

x = 40/2

x = 20

Son's age = 20 years

Father's age = 60 years
