Question

Rahul's age is 2/5 the of his mother's age today. After eight years Rahul's age will be half of
that of his mother. Find the difference in their age in years
a. 20
b. 24
27
d. 18​

Answer 1

Let the present age of the Rahul be x years.

So, present age of his mother is 6x years.

Given, rahul's age five years from now will be one-third of his mother's present age.

⇒x+5=2x

⇒5=2x−x

[Transposing x to RHS]

⇒x=5

Therefore, present age of Rahul is 5 years and that of his mother is 6×5=30 years
