A man was 30 years old in 1990 and 18 years old in 2000. How is this possible?
Correct answer: C. Born in BC
- A. Time travel
- B. Misprint
- C. Born in BC
- D. He's lying
Explanation
The correct answer is that the man was born in BC. This means he was born in 19 BC, making him 30 years old in 1990 AD and 18 years old in 2000 AD. The other options do not provide a logical explanation: time travel is fictional, a misprint is irrelevant here, and assuming he is lying does not solve the logical puzzle.

About Logical Problems
Logical problems present several conditions about people, objects, events or choices and require their possible arrangements to be tested. They cover constraint-based reasoning, rankings, matching, grouping, scheduling and elimination, with attention to the difference between a complete solution and a possibility that merely satisfies one condition.
