Question

Mohan is twice as old as his brother. 3 years ago, Mohan's age was 3 times his brothers age. Calculate Mohan's present age.

Answer 1

Present age of brother=x
present age of Mohan=2x
3 years ago
age of brother=x-3
Age of Mohan=3(x-3)


Age of Mohan 3 years ago+3=present age of Mohan

3(x-3)+3=2x
3x-6=2x
So x=6

So Mohan's present age=2x=12
