Question

A father is 20 years older than his son. After 5yrs the age of father will be twice of his son.Find the present age of Father and son?​

Answer 1

Answer:

Let F be the father's age and S  be the son's age.

The first statement can bebtranskatedas F = S + 20.

The second statement is F - 5 = 3(S - 5)

Plugging the first equation into the second

S + 20 - 5 = 3(S - 5)

S + 15 = 3(S - 5)

S + 15 = 3S - 15

S + 30 = 3S

30 = 2S

15 = S

So the son is 15, and the father is 35. 5 years ago, they were 10 and 30.
