Grok 3 Beta's response to the Logic Puzzle challenge.
Sally (a girl) has 3 brothers. Each brother has 2 sisters. How many sisters does Sally have?
Let's break this down step by step. Sally is a girl and has 3 brothers. The problem states that each of these brothers has 2 sisters.
Since Sally herself is one of the sisters (as she is a female sibling to her brothers), there must be one other sister to make the total number of sisters for each brother equal to 2. Therefore, the family consists of 2 girls (Sally and her sister) and 3 boys (Sally's brothers).
From Sally's perspective, the number of sisters she has is the number of other girls in the family besides herself. Since there is 1 other girl, Sally has 1 sister.
Answer: Sally has 1 sister.
