Answer:

Sonal=35 yrs

Manoj=25 yrs

Step-by-step explanation:

Let the ratio be x.

Sonal age will be 7x

Manoj age will be 5x

After 10 yrs,

Sonal will be (7x + 10)

Manoj will be (5x + 10)

The ratio of their ages after 10 yrs will be 9:7

(7x + 10) = 9

(5x + 10) 7

7 (7x + 10) = 9 (5x + 10)

49x + 70= 45x + 90

49x - 45x = 90 - 70

4x= 20

x= 20

4

x=5

Present age of Sonal= 7x

= 7 × 5

=35 yrs

Present age of Manoj= 5x

= 5×5

= 25 yrs
