I'm sure we got some smart young lads that browse B.net so this puzzle shouldn't be a problem for you fellows. Here's the situation: You are on an epic adventure (who knows why) and as you walk along the path you come across this scene: [url]http://www.dropbox.com/s/jz76oswbakpbklu/Puzzle.jpg[/url] Here's the deal: One door is the one you need to continue your adventure, the other leads to certain death. [u]The object of the puzzle is to figure out which door is the right door.[/u] Now the two random guys, one of them [b]always tells the truth[/b], and the other [b]always lies[/b]. [u]You do not know which is which.[/u] You have [b]one[/b] question, to ask of [b]either[/b] of them. What you are trying to do is find one question, that will give you a 100% chance of knowing which door is the right one, without it mattering which guy you ask (the truth teller or the liar), remember you don't know who is who. Let the games begin. (I will try to find the source to this puzzle but I'm not sure it exists anymore)
