Answer 2

Let Ravi's present age be =X
15 years later=X+15
4 times of X = 4x
It is given that after 15 years Ravi's age will be 4 times his present age.
ATQ,we can write the equation as
: X+15=4X
or,15=4X-X
or,15=3X
or,X=15/3
or,X=5
Hence Ravi is now 5 years old.
Proof,
His present age=5
After 15 years his age will be 5+15=20
20 is 4 times of 5.
