Doorman #3 says, "I always tell the truth. My door leads to a pile of leaves."

Cordell Dawson · Answer 2

Make a table

3 scenarios

1.

if we assume that dorman1 tells truth and the other 2 lie then

1:leaves

2: leaves

3: money (lying both times)

no contradiction

2. if we assume that dorman 2 tells truth and the other 2 lie then

1. money

2. money

3. money

contradiction, there should only be 1 money

3. assume dorman 3 tells truth and the other 2 lie

1. money

2. leaves

3. leaves

either dorman 1 or 3 has the money
