The 12 Guys On An Island Riddle
Riddle:
There are 12 guys on an island. One of them weighs slightly more (or less) than the others, but you don’t know which. You have a balance scale and can only use it three times. How do you find the odd man out?
- Answer: You can find the odd man in three weighings using a divide-and-test method.
- Explanation:
- Divide the 12 men into three groups of four.
- Weigh two groups (4 vs 4).
- If they balance, the odd one is in the remaining four. If not, it’s in the heavier or lighter side depending on the result.
- Split the four into two and weigh again. Continue narrowing down.
- By the third weighing, you’ll identify the different one and whether he’s heavier or lighter.
This puzzle uses logical deduction — not math, but reasoning — making it a timeless test of problem-solving.
