Question

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

Answer 1

5

Explanation:

Ravi's age is x. Fifteen years plus x will equal four times x.

15 + x = 4x

(15 + x) - x = 4x - x

15 = 3x

15/3 = (3x/3)

5 = x

Answer 2

5 years old

Explanation:

Ravi = x

x + 15 = 4x

-3x = -15

x = 5
