4X = X+15

4X - X = 15

3X = 15

X = 5

Answer 2

At present:

Age of Ravi = x years

After 15 years:

Age of Ravi = x + 15 years

According to the problem given,

Fifteen years from now Ravi's age will be 4 times his present age.

=> 4x = x + 15

=> 4x - x = 15

=> 3x = 15

=> x = 5

Therefore,

Present age of Ravi = 5 years
