Question

The sum of the ages of Father and son is 51 years. Eight years ago, the product of their ages was three times the father's age at that time. What is the present age of Father? (Check my earlier questions too, they are unanswered too)

Answer 1

Step-by-step explanation:

let age of father be x and son be y.

x+y=51.......1

8 years ago,

Father age=x-8, son age=y-8

(x-8)(y-8)=3(x-8)

y-8=3 since, x-8 get cancelled out

y=11 put in 1

therefore, x+11=51

x=40

therefore father age is 40 years
