A family consists of a father, mother, and son. The ratio of their present ages is 8 : 5 : 2 and the present age of the father is 48 years. What will be the average age of the family after 3 years?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 33 years.
Mother's present age = (48/8) × 5 = 30 years
Son's present age = (48/8) × 2 = 12 years
Total age of the family after 3 years = (48 + 3) + (30 + 3) + (12 + 3) = 51 + 33 + 15 = 99 years
Average age = 99/3 = 33 years
