Solar Pro 3 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?
Answer: Sally has 1 sister.
Explanation
If there were only Sally and her three brothers, each brother would have only one sister (Sally).
Since each brother is said to have two sisters, there must be one more girl besides Sally.
That extra girl is also a sister to Sally (they are siblings), so Sally’s sister count is:
Hence Sally has one sister. (The total number of girls in the family is 2, Sally plus her one sister.)
