  • Three brothers, two sisters each. Count carefully.

    Seed 2.0 Lite: The answer is 1 sister. Breakdown of the riddle: All the brothers are part of the same immediate family, so they share the same sisters. Each brother only has 2 total sisters across the whole family. One of those 2 sisters is Sally herself, so Sally only has 1 other sister.

    Solar Pro 3: Answer: Sally has 1 sister. Explanation Sally is a girl, and she has three brothers. Each brother has exactly two sisters. For a brother, the two sisters are the other girls in the family. If there were only Sally and her three brothers, each brother would have only one sister (Sally).
