Question

What is the solution of sunitha is twice as old as her brother. In 6 years time, the sum of their ages will be 39. What are their ages now?

Answer 1

Let her brother's age be x years.
Sunitha's age 2x years.

6 years hence,
Her brother's age will be (x + 6).
Her age will be (2x + 6).

According to given condition,

(x + 6) + (2x + 6) = 39
$\Rightarrow$3x + 12 = 39
$\Rightarrow$3x = 27
$\Rightarrow$x = 9 (Her brother's age)

Sunitha's age = 2x = 18 years
