The ratio of a father’s age to his son’s age is 3 : 2 The product of the numbers representing their age is 486. The ratio of their ages after 5 years will be:
Answer & explanation
Correct answer: option 4
ATQ,
Lets assume father's age is 3x and son's age is 2x
Given, Product of their ages ⇒ (3x) x (2x) = 486
⇒ 6x² = 486
⇒ x = 9
Father's age after 5 years = 32
Son's age after 5 years = 23
Ratio of ages of father and son = 32:23
