Previous Year Question (PYQs)
The average age of husband and wife was 22 years when they were married five years back. What is the present average age of the family if they have a three year old child?
Solution
Five years ago:
Average of husband and wife = 22 ⇒ sum of ages then = 22 × 2 = 44
After 5 years, each becomes 5 years older:
New sum (husband + wife) = 44 + 5 + 5 = 54
Child’s age = 3 ⇒ total of family ages now = 54 + 3 = 57
Average age of family now = 57 ÷ 3 = 19 years
