Question

Arun is now 20 years old and Leela is now 4 years old.In ow many years will Arun be twice as old as Leela?

Answer 1

Step-by-step explanation:

let us suppose that arun will be twice as old as leela after x years

Then, Arun age will be (20+x)years.

And, Leela age will be (4+x)years.

At that time, Arun's age will be twice Leela's Age

20+x=2(4+x)

20+x=8+2x

20-8=2x-x

12=x
