Let present age of Son be x years
So, present age of Man be 4x years
After 16 years »
Son's age = (x + 16) years
Man's age = (4x + 16) years
According to Question,
(4x + 16) = 2(x + 16)
⇒ 4x + 16 = 2x + 32
⇒ 4x - 2x = 32 - 16
⇒ 2x = 16
⇒ x = 16 / 2
⇒ x = 8
Required present Ages »
Son's age = x = 8 years
Man's age = 4x = 4(8) = 32 years
Hence, the present age of the Man is 32 years and the present age of the Son is 8 years.
