JonM Posted February 23, 2006 Share Posted February 23, 2006 This one is a pretty well known logic question, but probably the hardest of its kind I've come across... I figure I'll post it incase some people don't know about it Your in a hallway with two doors. One leads to hell, one leads to heaven. There is a guard standing by each door. One of the guards always tells the truth and the other one always lies. You have one question to ask, what will it be? (assuming you want to go to heaven) Thats the all info you have... Don't google it if you know any other ones that are harder than this post them up... Link to comment Share on other sites More sharing options...

JonM Posted February 23, 2006 Author Share Posted February 23, 2006 "What's 2+2?" Doesnt help you get to heaven... Just tells you which one lies/tells the truth. (you don't know which guard is guarding which door) Link to comment Share on other sites More sharing options...
Cap'n Refsmmat Posted February 23, 2006 Share Posted February 23, 2006 "What would the other guy say, if I asked him, 'Does this door go to hell?'" If he says, "He'd say 'yes'" then take it, because it's the door to heaven. Link to comment Share on other sites More sharing options...
Y-S Posted February 23, 2006 Share Posted February 23, 2006 ^^^ what if that guard said tru? Link to comment Share on other sites More sharing options...
Cap'n Refsmmat Posted February 23, 2006 Share Posted February 23, 2006 It's guaranteed that he's lying, because if you ask the one that lies, he'll tell you the opposite of the truth, and if you ask the one that tells the truth, he'll tell you the opposite anyways (because that's what the other would say).

JonM Posted February 23, 2006 Author Share Posted February 23, 2006 right!... or an easier way: "Which door would the other guard say leads to hell?" Link to comment Share on other sites More sharing options...
NPK Posted February 23, 2006 Share Posted February 23, 2006 Anyone seen Labyrinth? The scene where she has the same problem with 2 talking doorknobs? Link to comment Share on other sites More sharing options...
Sisyphus Posted February 28, 2006 Share Posted February 28, 2006 I've seen that same question in kid's cartoon shows. It's probably the most common "logic problem" in the world. Also, has anyone else seen The Enigma of Kaspar Hauser? Link to comment Share on other sites More sharing options...
