Let the present ages of Sonal and Manoj be 7a and 5a
After 10 years,
Sonal's age = 7a+10
Manoj's age = 5a + 10
According to question
(7a+10)/(5a+10)= 9/7
=> 49a + 70 = 45a+90
=> 4a = 20
=> a = 5
Sonal's present age = 35 years
Manoj's present age = 25 years
After 10 years,
Sonal's age = 7a+10
Manoj's age = 5a + 10
According to question
(7a+10)/(5a+10)= 9/7
=> 49a + 70 = 45a+90
=> 4a = 20
=> a = 5
Sonal's present age = 35 years
Manoj's present age = 25 years
