  • Three brothers, two sisters each. Count carefully.

    Grok 4.20 Beta: Sally has 2 sisters. Explanation: Sally is a girl, so she is one of the sisters. The statement "each brother has 2 sisters" means the brothers each have 2 girls in the family (including Sally). Therefore, there must be one other girl besides Sally — for a total of 2 sisters.

    Amazon Nova 2 Lite: To determine how many sisters Sally has, let's analyze the information step by step: Sally is a girl, and she has 3 brothers. This means there are 3 boys in the family (her brothers). Each brother has 2 sisters. From the perspective of any one brother, he sees 2 girls in the family.
