A family consists of a grandfather, a grandmother, their two sons, the wives of both sons, and two grandchildren born to each son (all four grandchildren are boys). How many persons are there in the family?
The family has 10 persons: two grandparents, two sons, two daughters-in-law and four grandchildren. Adding 2 + 2 + 2 + 4 gives 10. Options with 12 or more wrongly add extra people not mentioned in the description.
- A10
- B12Correct
- C14
- D16
Explanation
Count each group: grandparents = 2, sons = 2, daughters-in-law = 2, grandchildren = 2 × 2 = 4. Total = 2 + 2 + 2 + 4 = 10... recheck: 2 + 2 + 2 + 4 = 10, so the correct total is 10.
