The average age of a man and his son is 56 years. The ratio of their ages is 11 : 5. What is the son's age?
Answer & explanation
Correct answer: option 2
Average of a man and his son = 56 years
Therefore, sum of age of a man and his son = 56 × 2 = 112 years
ATQ,
⇒ 11x + 5x = 112
⇒ x = 7
Son's age ⇒ 5 × 7 = 35 years
