There are two doors
One holds a hostage and the
other will set off a trap and
kill you.
Your mission is to save this
hostage
dleh
Additionally, there are two
blindman. They know which
door the hostage is in. But there
are two problems. They will only
answer a question if paid 25
cents. Unfortunately, you only
have one quarter so you can
have one single question to
either man of your choice.
Problem two, one of the men
will always tell the truth and
one will always lie to you when
asked a question. The problem
lies in the fact you don' t know
which of the men is the liar.
satty ms pint watck

Guard, what would the other guard say if I asked him where his door leads? the opposite of his answer is the truth.
User avatar #729 to #8 - mikejj (01/25/2012) [-]
all they said is that one is a liar. he could just say "I don't know". he'd still (possibly) be lying and you would still have no idea which door to choose.
#1123 to #8 - surviver (01/26/2012) [-]
i get your idea on this question and yes it is the correct answer but i came up with that at first remembering labyrinth (awesome memory :D) but in an ironic way wouldnt both answer your question telling you that the other guard would say a lie?

that's what Sarah asks on the Labyrinth!
#345 to #8 - Penn (01/25/2012) [-]
I'm trying to figure it out but I need to write it down.
-I pick man on left
-Ask him "What would the other guard say if I asked him where his door leads?"
-He says the other guard would say that his door leads to death
-If guy on left is liar then the right door is the one I should choose
-If guy on left is truthful then the left door is the one I should choose

Am I missing something?
User avatar #429 to #345 - UberCreep (01/25/2012) [-]
Assume Door 1 has the hostage.

Situation 1:
Man 1 is truthful.
Ask Man 1 that question.
Response is "Door 2 has the hostage" (Since Man 2 would say Door 2 DOES have the hostage)
Pick Door 1.
Profit.

Situation 2:
Man 1 is a liar.
Ask question.
Man 1 says "Door 2 has the hostage" (Since Man 2 would say that Door 2 does NOT have the hostage)
Pick Door 1
Profit
#1080 to #429 - Penn (01/26/2012) [-]
But you don't know if Man 1 is a liar or if he's truthful, which makes your argument invalid (no disrespect). Let's say this:
Based on what was given in this thread:
I go up to Man 1 and ask him "What would Man 2 say if I asked him where his door leads?"
Man 1: Man 2 would say that his door leads to the hostage.
And that's it. I don't have any more information. I don't know if Man 1 is the liar or the non-liar nor do I know which door leads to the hostage.


User avatar #451 to #429 - wiredguy (01/25/2012) [-]
So you create a double negative? No that's not exactly it...
Hm, I understand it, I just can't put it into words XD
User avatar #468 to #451 - wiredguy (01/25/2012) [-]
IGETITIGETIT!
RIGHT, LOGIC TIME BITCHES.

There are two questions involved here:
Question 1: "What would the other man say if I asked him which door the hostage was behind?"

Question 2: "Which door is the hostage behind?"

Whichever one you choose, you are receiving the answer you would get if you asked the liar question 2.

Situation 1:
You ask the true guy.
Ask him question 1.
He says whatever the liar would say.
You have the liar's answer to question 2, pick other door.

Situation 2:
You ask the liar.
Ask him question 1.
He says the opposite of what the true man would say (there's that double negative that confused me).
Hence the answer is also a lie. You once again have the liars answer to question 2, pick other door.

There we go. I know you already understood that, I just felt so proud for getting it XD
User avatar #581 to #468 - volleys (01/25/2012) [-]
But how do you know who you asked... you would get it wrong 50% of the time.
#598 to #581 - anonymousforlife (01/25/2012) [-]
No you wouldn't.

If we say guy #1 always tells the truth, and #2 always lies.
Guy number #2 would say the wrong door.
Guy number #1 would say the right door.
So if I ask guy #1 what #2 would say, he knows that guy #2 is lying, so he would say the wrong door. Therefore, I take the opposite of what he says.

If we say I ask #2, he would know, that #1 would say the right door. But since #2 is a liar, he says the opposite of what #1 would, therefore the wrong door.

HOpe you understand it.

You wouldn't know, but no matter which of them you asked, you would get the wrong answer

Tie a string onto the Quarter and ask your question, then after giving the coin, pull it back up and the guy won't notice. He's blind. Continue for infinite questions.

you ask one of them witch door the other man would say the hostage is in. whatever they say you take the other door.   
logic being,  if you end up having the  one that lies, he wont tell you the truth cus thats not how he rolls, so he tells you the wrong door,  you ask the one telling the truth he knows the other one would lie and tell you the wrong door. they both will tell you the wrong door, so now you can pick the right one.

If you get the liar then he will lie and actually say which door the hostage is in but then its a never ending paradox with your solution.
User avatar #435 to #341 - santay (01/25/2012) [-]
think it through another time.
User avatar #440 to #435 - sunice (01/25/2012) [-]
No because in order for the one to lie, he has to say the one the truth teller will say. In order for the truth teller to say the one the liar will say they have to just say it regardless of where the person is. So the truth teller will say what the liar will say causing the liar to say the other door and its never ending.
User avatar #450 to #440 - santay (01/25/2012) [-]
Okay. Let's say the Hostage was in door 1. and person 1 was the truth.
Person 1 would say: "person 2 would say door 2"
Person 2 would say "Person 1 would say door 2"
So it's always the opposite of what they say.
User avatar #453 to #450 - sunice (01/25/2012) [-]
Person 2 lies so they would say that person 1 would say door 1
User avatar #459 to #453 - santay (01/25/2012) [-]
But you're asking what the other person would say. Since person 1 knows its door 1 and would say it was door 1 which is the truth. Person 2 lies and would say "Person 1 would say door 2" making it the opposite both times... Get it?
User avatar #467 to #459 - sunice (01/25/2012) [-]
You said person 1 who tells the truth would say that person 2 says door 2
but in order for person 2 to lie they have to say that person 1 will say door 1 but that makes the truth teller a liar. So either way they both tell the truth or they both lie. That doesnt work since one has to lie and one has to tell the truth.
#513 to #467 - santay (01/25/2012) [-]
You really don't get this... I'm sorry, this guy is correct and I really don't know how to explain it any further.

The problem in your thinking is that you're going in circles. The question isn't, "What would the other blind man say if he had to say what you would say?" but it is "What would the other man say?" Stop going in circles, and it would make sense to you. Let me go over it with you.
Let door 1 be the hostage door. You don't know which man will lie or which will tell the truth, but you know they will both end up lying if you ask either of them what the other man will say.
IF YOU ASK THE TRUTH-TELLER: He will truthfully tell you what the liar will say. The liar would lie, and say that the hostage door is door 2. The truth-teller, then, would tell you, "If you asked the other man what he would say was the right door, he would say door 2."
IF YOU ASK THE LIAR: He will lie about what the truth-teller will say. The truth-teller would tell you the truth, and say the hostage door is door 1. However, the liar would tell you the opposite of what the truth-teller will say. The liar, then, would say "If you asked the other man what door is good, he would say door 2."
So you see, the truth-teller tells the truth about the liar, and the liar lies about the truth-teller. No matter who you ask, the will tell you the wrong door. So you will know the correct door is the opposite of what they say, every time!

User avatar #433 to #144 - dwraith (01/25/2012) [-]
No, he's telling you WHAT the liar would say. He's not telling you that it's the correct door. He's just saying what the other person would say.
User avatar #574 to #144 - volleys (01/25/2012) [-]
If you ask the truth he would tell you the wrong door, but you don't know who you asked so... no way.

Easy.
1. Ask one blind man what is behind the door and put the quarter in his cup.
2. Next take the quarter out of the cup and since he is blind he won't know.
3. Give the second man the quarter for his answer.
4. Figure out that having both answers doesn't help you.
5. Push one of them through the door and see what happens.
6. If he dies push in the other one and watch him die too and your work is done.

Quite simple.

I ask one of them "where will the other blind man tell me to go?"
The truthfull man will point at the trap, being honest and all, as the lying will also point at the trap, becouse he is a lying bastard.

I then rescue the hostage, get laid, and die of a heart-attack while having sex.


IT WAS ALL A TRAP!

If I knew it cost ¢25 I'd ask one the question how much it cost to ask a question, most likely they wouldn't count that as the question. If the person I asked the cost said anything but ¢25 I'd know he was the liar, I would then know who told the truth and would proceed to ask him what door the hostage was behind.

User avatar #718 to #712 - Mantis (01/25/2012) [-]
For one thing, it's they're not their, that bugged me, secondly, for all we know when the blind man takes the quater he tosses it down a well or ingests it. It would be pretty hard to take get your quater back from the stomach of a blind man especially without him knowing.
User avatar #331 to #20 - ozobradleyozo (01/25/2012) [-]
You only have 25 cents, therefore you can only ask one question. Your solution is flawed.

User avatar #490 to #331 - Mantis (01/25/2012) [-]
"If I knew it cost ¢25 I'd ask one the question how much it cost to ask a question, most likely they wouldn't count that as the question." I have another solution as well. -


Give the ¢25 to one and ask what door the hostage is behind, regardless of the answer ask the blind man for your ¢25 back, if he says you can have it back he's the liar and you should take the opposite of his advice, if he says you can't have your ¢25 back he's telling the truth and you should choose the door he told you.
User avatar #388 to #331 - DanR (01/25/2012) [-]
he goes up to ask a question, but first must know how much it costs, so asking how much a question costs should be free or else the blind men would never make any money
