Answer 1

Answer:

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

Answer 2

Answer:

Rahul = x

Mother = 6x

After 5 years,

(x + 5) = 2/7 (6x + 5)

x + 5 = 12x/7 + 10/7

7x + 35 = 12x + 10

5x = 25

x = 5

Rahul = 5 years

Mother = 30 years
