A man has 9 sons. Each son has a sister. How many people are in the family?🤔
The Mathematical Breakdown & Answer 🧠
The correct answer is 11 people (assuming we are counting the man, his sons, and his daughter, as mentioned directly in the text). If you include a mother, the answer would be 12.
Here is how the logic works:
The Man: 1 person
The 9 Sons: 9 people
The Sister: 1 person. Since all 9 boys are brothers in the same family, they all share the same single sister. "Each son has a sister" doesn't mean 9 different sisters; it means they all have that one sister in common!
So, the core family headcount is 1 \Man+ 9 \Sons+ 1 \Sister = 11
