  • Three brothers, two sisters each. Count carefully.

    Gemini 3.1 Pro Preview: Sally has 1 sister. Here is the breakdown: If each brother has 2 sisters, that means there are 2 girls in the family total. Since Sally is one of those girls, the other girl is her 1 sister.

    Qwen Plus 0728: Let's break this down step by step: Sally has 3 brothers. Each brother has 2 sisters. Now, the key is to realize that all the brothers share the same siblings. So, when it says each brother has 2 sisters, those sisters are the same for all brothers. Sally is one of those sisters. So who is the other sister?
