Answer:
Sonal-35yrs , Manoj-25yrs
Step-by-step explanation:
Let the present Age of Sonal and Manoj be 7x and 5x respectively.
Ten years later their ages will be (7x + 10) and (5x + 10)
Given the ratio of the ages after 10 years = 9:7
Assume the ages as 9x and 7x
∴7x + 10 + 5x + 10 = 9x + 7x
⇒12x - 16x = -20
⇒-4x = -20
⇒x = -20/-4
∴x = 5
Therefore the present age of Sonal = 7x = 7 * 5 = 35 years
And the present age of Manoj = 5x = 5 * 5 = 25 years
