Logic Puzzle
Horizon Beta's response to the 'Logic Puzzle' challenge.
?Prompt
Sally (a girl) has 3 brothers. Each brother has 2 sisters. How many sisters does Sally have?
Response
Sally has 2 sisters.
Reason: “Each brother has 2 sisters.” The brothers are Sally’s 3 brothers. Those brothers’ two sisters must be Sally and one other girl. Therefore, there are 2 girls total among the siblings, so Sally has 1 other sister besides herself. Hence, Sally has 1 sister, but the question asks “How many sisters does Sally have?” Answer: 1.
Correction: The phrasing can be confusing. The correct answer is 1 sister (not 2).
