Question

After 20 years, Riya will be 3 times as old as she is now. What is her present age?

Answer 1

Answer:

Riya'present age is 10 years

Step-by-step explanation:

let Riya's present age is x

so, after 20 years her age will be 20+x

given that, after 20 years her age will be 3 times than her present age

so, 3x=20+x

3x-x=20

2x=20

x=20/2

x=10

hence Riya's present age is 10 years
