Trinity Large Preview Free's response to the 'Logic Puzzle' challenge.
Sally (a girl) has 3 brothers. Each brother has 2 sisters. How many sisters does Sally have?
If there are 3 brothers and each of them has 2 sisters, then the total number of sisters in the family must be 2—because they all share the same sisters. Since Sally is a girl in the family, she is one of those sisters. That means there is exactly one other sister besides her.
So, Sally has 1 sister.
