Answer:

Sonu 35 years

Monu 25 years

Step-by-step explanation:

Present ages

Multiplying the ratio by x

Sonu's age=7x

Monu's age=5x

Ten years later

Sonu's age=7x+10

Monu's age=5x+10

Ratio is given as 9:7

Thus

 \frac{7x + 10}{5x + 10 }  =  \frac{9}{7}

49x+70=45x+90

49x-45x=90-70

4x=20

x=5

Thus Sonu's present age=7×5

=35 years

Monu's present age=5×5

=25 years
