A family has a grandfather, his wife, their two sons, the wives of both sons, and two children for each son. How many persons are there in the family?
The family has 12 persons: the grandfather and his wife (2), their two sons (2), the sons' wives (2), and four grandchildren, two for each son. Adding 2 + 2 + 2 + 4 gives twelve.
- A10
- B12Correct
- C14
- D8
Explanation
Count: grandfather and wife = 2; two sons = 2; their wives = 2; children = 2 x 2 = 4. Total = 2 + 2 + 2 + 4 = 12. The option 10 omits the grandparents' pair or the wives' count and so is too low.
