There are five people in a room. Each person is either a knight, who always tells the truth, or a liar, who always lies. Each person is asked the following question: How many liars are among you? The answers are: "one", "two", "three", "four", "five".

How many liars are in the room?

there are four liars

Four liars, one knight. I believe this is the only combination that works, because if there were more than one knight present, some of the answers would have been the same. Since all the answers are different, there is only one who is telling the truth.

Nice puzzle!

I agree with the above that there are 4 liars, 1 knight.

If there were 0 Knights, then the liar who said there were 5 liars would be telling the truth, so that doesn't work...and if there were more than 1 knight, than 2 answers would have been the same... So, the person who said "four" is your knight, the rest are liars.
