?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.
Given information:
- Sally is a girl
- Sally has 3 brothers
Now, each brother has 2 sisters.
If each of Sally's brothers has 2 sisters, and Sally is one of those sisters, then there must be one more sister besides Sally.
Let me verify:
- Total sisters in the family: Sally + 1 other sister = 2 sisters
- Each of the 3 brothers would have these same 2 sisters
- This checks out ✓
Therefore, Sally has 1 sister.
