Question

Fifteen years from now Ravi’s age will be four times his present age. What is Ravi’s

present age?​

Answer 1

Answer:

Let Ravi's present age be x years.

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

⇒3x=15

⇒x=

3

15

=5

Hence, Ravi's present age is 5 years.

Answer 2

Let the present age of Ravi be x.

Fifteen years later, Ravi age will be x+15 years.

According to the question,

x + 15 = 4x

⇒ 4x – x = 15

⇒ 3x = 15

⇒ x = 15/3

⇒ x = 5

Therefore, Present age of Ravi = 5 years.
