Question

A and B are 3 years and 2 years old respectively. Their father is 40 years. After how many years, fathers age would be twice of combined age of A and B?

Answer 1

Answer: 10 years

Step-by-step explanation:

Let number of years be x.

2{ (x+3)+(x+2) } = 40+x

2(2x+5) = 40+x

4x+10=40+x

3x=30

x = 30/3 =10
