Mr. John is three times as old as his son. In 15 years he will be only twice as old as his son. Find their Present
ages.​

Answer 1

Step-by-step explanation:

let the boy be x

Father =3x

given \\ x + 12 = 2(x + 12) \\ x + 12 = 2x + 24 \\

or

2x + 24 = 3x + 12 \\ - 12 + 24 = 3x - 2x \\ = > 12 = x

father =3x

3x = 3 \times 12 = 36

present age of father is 36 and son is 12
