A family consists of two parents and three children. The average age of the parents is 32 years, and that of the children is 5 years. What is the average age of the family?
Show answer & explanation
Correct answer: B
Explanation
Given:
Parents = 2, Average age = 32 years
Children = 3, Average age = 5 years
According to the formula:
Average = (Total Age) / (Total Number of People)
Total age of parents = 2 × 32 = 64
Total age of children = 3 × 5 = 15
Total age = 64 + 15 = 79
Total number of people = 2 + 3 = 5
Average = 79 / 5 = 15.8 years
