Question

24.The age of Jack will be three times
that of his son.After 12 years, his age
will be twice as that of his son. What
are their present ages?

Answer 1

Answer:

Let son's present age = x

Jack's present age = 3x

After 12 years,

Son's age = x+12

Jack's age = 3x+12

ATQ, 3x+12 = 2(x+12)

3x+12 = 2x+24

3x-2x = 24-12

x = 12

Son's present age = 12 years

Jack's present age = 3×12 = 36 years
