Logic Puzzle
Nova Premier V1's response to the 'Logic Puzzle' challenge.
?Prompt
Sally (a girl) has 3 brothers. Each brother has 2 sisters. How many sisters does Sally have?
Response
To determine how many sisters Sally has, we can break down the information given in the problem step by step.
- Identify the number of brothers Sally has. According to the problem, Sally has 3 brothers.
- Each of Sally's brothers has 2 sisters. Since Sally is one of the sisters, the other sister must be the same for all brothers. Therefore, the other sister is the same person, not a different sister for each brother.
Let's denote the sisters as follows:
- Sally is one sister.
- Let's call the other sister ( S ).
Since each brother has 2 sisters and Sally is one of them, the other sister must be ( S ). This means that Sally and ( S ) are the only two sisters.
Thus, Sally has 1 sister.
The answer is (\boxed{1}).
