Verified Answer
Ten years ago, the ages of the members of a joint family of eight peop...
Ten years ago, the total age of the family is 231 years.
Seven years ago, (Just before the death of the first person), the total age of the family would have been 231+8*3 = 231+24 = 255.
After the death of one member and the birth of a child, the total age is 195 years.
Four years ago, after the death of one member and birth of another child, the total age of the family is 195+24-60 = 159 years.
The current total age of the family is = 8×4 + 159 = 191 years
The average age is 191/8 = 23.875 years = 24 years (approx)

Calculation of total ages 10 years ago:
- Ten years ago, the total ages of the 8 family members added up to 231 years.

Changes in the family:
- Three years later, one member died at the age of 60 and a child was born.
- After another three years, one more member died at the age of 60 and another child was born.

Current total age of the family:
- Total age of the family now = Total age 10 years ago + 6 (ages of the two deceased members) - 120 (ages of the two newborn children)
- Total age of the family now = 231 + 6 - 120
- Total age of the family now = 117 years

Current average age of the family:
- Current average age = Total age of the family now / Number of family members
- Current average age = 117 / 8
- Current average age ≈ 14.63 years

Approximation:
- Since the question asks for the nearest answer, the current average age of the family is closest to 24 years (D).
