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

1.	Fifteen years from now Ravi’s age will be four times his present age. What is Ravi’s present age?
Answer» Let Ravi’s present age be x years. Fifteen years later, Ravi’s age = 4 × His present age x + 15 = 4x On transposing x to R.H.S, we obtain 15 = 4x − x 15 = 3x On dividing both sides by 3, we obtain 15/3 = 3x/3 5 = x Hence, Ravi’s present age = 5 years

Answer»

Let Ravi’s present age be x years.

Fifteen years later, Ravi’s age = 4 × His present age x + 15 = 4x

On transposing x to R.H.S, we obtain

15 = 4x − x

15 = 3x

On dividing both sides by 3, we obtain

15/3 = 3x/3

5 = x

Hence, Ravi’s present age = 5 years
