A man's age is now 3 times his son's age. Eight years back, the man's age was 5 times his son's age. What is the present age of the son?
Solution
Correct Answer: Option D
Let Man's son's present age = x
Man's present age = 3x
According to the question
5(x - 8) = 3x - 8
⇒ 5x - 40 = 3x - 8
⇒ 5x - 3x = 40 - 8
⇒ 2x = 32
x = 16
