​

Answer 1

Answer:

Mohan's present age= 35 and Sohan's present age= 25

Step-by-step explanation:

Ratio of their ages= 7:5

Let the common factor be 'x'.

According to the question,

⇒ 7x+10+5x+10= 9x+7x

⇒ 12x+20= 16x

⇒ 20= 16x-12x

⇒ x= 20/4

∴ x= 5

∴ Their ages⇒  7x= 7*5= 35

                          5x=5*5= 25
