of father to that of son is 7:2.
After 10 years their ages will be
in the ratio of 9:4. The present
ages of the father is * 9th standard
​

Answer 1

Answer:

let ages of father and son be 7x and 2x

after 10 years

age of father = 7x + 10

age of son = 2x + 10

7x+10/2x+10 = 9/4

4(7x+10) = 9(2x+10)

28x+40 = 18x+90

10x = 50

x = 5

present age of father = 7×5 = 35years
