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
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
