Answer 2

Let the ages of Rahul and Romit be x and y respectively.

As per the question,
Rahul is twice old as Romit
>>x=2y____(1)

The difference of their age is 9
>>x-9=y____(2) [Since x>y]
x=y+9___(3)

Substitute (3) to (1)
y+9=2y
y=9
x=2*9=18[Using (1)]

Thus, Rahul is 18years old and Romit is 9years old.
