The ratio of the age of a father and his son is 3 : 1. If the product of their ages is 432, then what is the sum of their ages?
Answer & explanation
Correct answer: option 2
ATQ,
Let the ratio be x
So, age of father is 3x and age of son is x
Given, Product of their ages = (3x) × (x) = 432
⇒ 3x² = 432
⇒ x = 12
Age of father = 3×12 = 36
Age of son = 12
Sum of ages of the father and son = 36+12 = 48 years
