Door 2 says: The money is not behind door 3.

Door 3 says: Door 1 is lying.

Which door is the money behind if only one door is telling the truth?

### Answer

If door 1 is telling the truth, then the money is behind door 2. That means door 2 is lying, and if door 2 is lying, then the money is behind door 3. The money is only behind one door, so door 1 is lying.If door 1 is lying, then door 3 has to be telling the truth. Since only one door is telling the truth, door 2 is lying, which means the money is behind door 3.

Answer: Door 3.
