Ten years ago, the ages of the members of a joint family of eight people added up to 231 years. Three years later, one member died at the age of 60 years and a child was born during the same year. After another three years, one more member died, again at 60, and a child was born during the same year. The current average of this eight-member joint family is nearest to

### Note

The sum of the ages of all 8 members 10 years ago = 231 years.

The sum of the ages of all members, 7 years ago = [{231 + (8 × 3)} – 60] years = 195 years.

The sum of the ages of all members, 4 years ago = [{195 + (8 × 3)} – 60] years = 159 years.

Sum of the present ages of all 8 members = {159 + (8 × 4)} years = 191 years.

Current average age = (191/8) years = 23.8 yeas =24 years(appr).
