Answer 1

Answer:

5 years

Step-by-step explanation:

After 15 years, his age will be (x+15) years.

It is given that after 15 years, Ravi's age will be four times his present age.

∴4x=x+15

⇒4x−x=15

⇒x=

3

15

=5

Answer 2

let the present age be x

therefore the age after 15 years be 4 x

equation =

x = 15 /100 of 4 x

x = 15 / 25x

x( 25/15x )

5/3
