QUESTION: 39

The father’s age is twice that of the elder son. Ten years hence the age of the father will be three times that of the younger son. If the difference between the ages of the two sons is 15 years, then the father’s age?

Solution: Let "x" be the present age of the elder son.

Then the father's present age is 2x, while the younger son's present age is (x-15).

In 10 years: The father's age will be (2x)+10.

the younger son's age will be (x-15) + 10 = x-5.

On the other side, in ten years, the father’s age will be 3(x-5).

Thus you get an equation

⇨ 2x + 10 = 3(x-5).

Simplify and solve for x:

⇨ 2x + 10 = 3x - 15

⇨ 10 + 15 = 3x - 2x

⇨ x = 25.

The elder son's present age is 25 years.

The younger son's present age is 25-15 = 10 years.

The father's present age is 2×25 = 50 years.
