👪 Family Age Calculation 👫
Let’s break it down step by step:
Grandparents’ total age = 2 × 67 = 134 years
Parents’ total age = 2 × 35 = 70 years
Grandchildren’s total age = 3 × 6 = 18 years
Total family age = 134 + 70 + 18 = 222 years
Total family members = 2 + 2 + 3 = 7
Average age of the family = Total family age / Total family members
= 222 years / 7
= 31.71 years
The average age of the family is approximately 31.71 years. 👪
