A family consists of a father, mother and son. The ratio of their ages is 8 : 5 : 2 and the present age of the father is 48 years. What will be the average age of family after 3 years ?
Answer & explanation
Correct answer: option 3
ATQ,
Lets assume, present age of father = 8x
present age of mother = 5x
present age of son = 2x
Given ⇒ 8x = 48
⇒ x = 6
After 3 years, father's age = 51
mother's age = 33
son's age = 15
Average age of family, after 3 years = \(\frac{51 + 33 + 15}{3}\) = 33 years
