The average age of a husband and wife was 22 years when they married 5 years ago. What is the present average age of the family if they have a 3-year-old child?

The present average age of the family is 19 years.

At marriage the couple's total age = 2 x 22 = 44 years.

After 5 years both grow, so their total = 44 + 2 x 5 = 54 years.

Adding the 3-year-old child, the family total = 54 + 3 = 57 years.

Average = 57 / 3 = 19 years.
