Question

Sonu's mother is 30 years older than sonu.After 5 years, mother's age will be 3 times sonu's age.
what is the present age of sonu and his mother?

Answer 1

Let m = mother's age, so that m-30 is Sonu's age.

m+5 = 3 x (m-30+5) , and we start by simplifying the right side

m-5 = 3m-75

80 = 2m

m = 40

Sonu's mother is currently 40 (years old), and Sonu is currently 10.
