Logic Puzzle
Qwen3 Coder Plus'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
I need to figure out how many sisters Sally has.
Let me break this down step by step:
- Sally has 3 brothers
- Each brother has 2 sisters
Since Sally is one of the girls in the family, and each brother has 2 sisters, this means there are 2 sisters total that the brothers count.
One of those sisters is Sally herself, so there must be 1 additional sister.
Therefore, Sally has 1 sister.
To verify: Sally + 1 sister = 2 sisters total, and each of the 3 brothers correctly has 2 sisters (Sally and her sister).
