let the ages of Sonu and monu be 7x and 5x respectively and after ten yrs there ages will be 9x and 7x respectively

according to question

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

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

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

49x+70 = 45x +90

4x = 20 => x = 20/4 = 5 yrs

sonu's age = 7x = 7×5 = 35 yrs

monu's age = 5x = 5×5 = 25yrs
