Question

the ratio of father and son is 6:3 .Four year ago their ratio was 13:5. what is current age of them?​

Answer 1

Answer:

Let the present age of father and son be F and S. Therefore,

F/S = 6/1

F = 6S ….(1)

and after 5 years

(F+ 5)/(S+5) = 7/2

2F + 10 = 7S + 35

2(6S) + 10 = 7S + 35 [From (1)]

12S + 10 = 7S + 35

5S = 25

S = 5 years
