At first glance, this looks like a simple math puzzle, but the wording is designed to trick you.
The Puzzle:
I enter a room with 50 people.
A killer walks in and kills 30.
How many people are still in the room?
Answer: 52
Explanation:
- You entered the room, so that’s 1 person.
- There were already 50 people inside.
- A killer enters, adding 1 more person.
That makes 52 people in the room before the attack.
The killer then kills 30 people, but the question asks how many people are still in the room, not how many are still alive.
The 30 victims are still in the room, along with:
- You
- The killer
- The remaining 20 living people
So:
- 30 victims
- 20 survivors
- You (1)
- The killer (1)
Total: 52 people still in the room.
