Answer:
Let the age of Sonal be 7x years and age of Manoj be 5x years
10 years later their age will (7x+10) and (5x+10)
Given ratio of ages after 10 years=9:7
So now assume the ages be 9x and 7x
∴7x+10+5x+10=9x+7x
9x−5x=20
4x=20
x=5
So, the present age of Sonal=7x=7×5=35years
and the present age of Sonal=5x=5×5=25years
