Question

The product of Ramu's age (in years) five years ago and his age (in years) nine years later is 15. Determine Ramu's present age.

Answer 1

Let the present age of Ramu be x years.

Ramu's age 5 years ago = (x – 5) years

Ramu's age 9 years hence = (x + 9) years

Given, Ramu's age 5 years ago × Ramu's age 9 years hence = 15

Thus, the present age of Ramu is 6 years
