Question

Rahul is 34 years old and Anuj is 15 years old. After how many years will the age of
Rahul be twice that of Anuj?

explain ​

Answer 1

Let present age of A be x. And B be y. Then according to question age of B two years ago was (x-2)-2 i. e.

(y-2)=(x-2)-2

=> x-y=2 ——(1)

And present age of A is twice as B i. e.

x-2y=0 - - (2)

Solving two equation we get x=4 years and y=2 years

Hence age of A is 4 years
