rajeev  (13 years ago)

let son's present age is = x year
so son's age 5 year ago was (x-5)
and father's age was 5(x-5) that time
and after two years son's age would be (x+2)
and then father's age would be 3(x+2)
hence it is clear that 5(x-5)+7 = 3(x+2)
and after solving we get x = 12
so son's present age is 12 years and so father's present age is 5(12-5)+5=40
s0 the ratio of present age of father and son respectively is 40:12 or10:3
