Answer 2

Let Deepak's Age be 'x'
and his Brother's Age by 'y'

According to the Question,

x + y = 15 ______(1)
x - y = 3 ______(2)

Adding equation (1) and equation (2) we get

2x = 18

$\bf\large{\boxed{x=9}}$

Putting value of x in equation(2) we get,

9 - y = 3
-y = -6
y = 6

$\bf\large{\boxed{y\:=\:6}}$

Hence, Deepak is 9 years old and his brother is 6 years old.
