uhhh... :dunno:

[blah-blah-blah]

uhhh... :dunno:


i feel ya:dunno:

[trill]

was it worth a new thread?

[omgodzilla]

Ask the liar if he is lying about a certain door leading to death.

[murderface]

uhhhh...vtec?

[E-DUBB]

ask the guard to go through the door of death. i think

[blah-blah-blah]

yes its worth a new thread.

and we dont know who the liar is

[Skinny Steve]

:madfuck: Cant figure it out!

[Carl EBJR]

Ask the liar if he is lying about a certain door leading to death.
He doesn't know which guard is which though.

[Carl EBJR]

BAM, Ask one of the guards to walk out one of the doors and if that guard lives then the king knows which one to walk into regardless if they are lying or not because the guard will be dead or alive.

[Skinny Steve]

BAM, Ask one of the guards to walk out one of the doors and if lives then the king knows which one to walk into regardless if they are lying or not because the guard will be dead or alive.

Makes sence I guess....

[tien]

does the question have to be directed towards only one guard or can it be the same question for both at once? directions don't specify that

[Btec]

BAM, Ask one of the guards to walk out one of the doors and if that guard lives then the king knows which one to walk into regardless if they are lying or not because the guard will be dead or alive.

but he can only ask questions, not order them.. i think. correct me if im wrong. i wanna know!!! lol

[Carl EBJR]

wouldn't a question not be an order though? "Could you please walk through door number one?" Not what a king would ask but i am stumped

[tarantic]

Asking the guard to walk out door isn't asking him a question :)

Here's how it would have to be played out to live:

Iif you had to find out which of the guards was the truthful one and which was the liar, you would ask one "what would the other guard say if I asked him if you always tell the truth?" If the guard says no, you're clearly talking with the truthful one. thus, the question you need to ask one of them is "if I asked the guard next to you about which door leads to freedom, which one would he indicate?", you just choose the opposite door as to what he responds with. booya :hs: the key to this riddle was that you can count on one guard to ALWAYS be telling the truth and one ALWAYS telling lies no matter what.

Isn't that 2 questions though? :hsugh:

[tien]

^^^you smart fuck!!! :rofl:
no that's 2 questions

[tarantic]

That's two question's though

no, you only ask the last question to one of the guards. I included the first question as a pretense to clarify my answer (the if/then solution. if this is true, then _____ is the answer) http://www.houston-imports.com/forums/images/icons/icon14.gif

[E-DUBB]

no that's 2 questions

the question he said to ask was: if I asked the guard next to you about which door leads to freedom, which one would he indicate?

[tarantic]

precisely :thumb:

[E-DUBB]

But how do you know that guard who you're asking is the guard who is the one that is a liar?

:smack: confusing

damn, you just gave me a formula it makes sense though. Good job :thumb:

[tarantic]

But how do you know that guard who you're asking is the guard who is the one that is a liar?

you don't need to know which is which, that's the beauty :D based on the fact that one is lying 100% of the time, and one is telling the truth 100% of the time, you can take the opposite answer of either guard and it's the truth :) re-read my first post with the solution I came up with :thumb:

[Btec]

The classic answer (well, one of the classic answers -- there are a few) is to ask one of the guards "what would the other guard say if I asked him if your door was the correct one?" You see, if the guard you ask is honest, he would say that the other guard would claim the door led to death, because that would be a lie. If the guard you ask was the liar, he would lie and say the other guard would claim the door led to life. In either case, you can safely assume the opposite is true, and that tells you, logically, which door is the correct one.

woot! thanks man :D I had to clear my mind a couple times when trying to dish it out heh. this was a good one!

But how would you know which one to trust though?

yah, yall confused the hell out of me, i got it now!

[tarantic]

yah, yall confused the hell out of me, i got it now!

hehe wrd, had me rattled too! I used a computer science if/then method to try and validate the q/a processes I sketched down that the king could have with the guards. lol I am in uber nerd mode tonight :hsugh:

[Carl EBJR]

I would have never looked into a riddle unless someone on H-I posted it up. The power of H-I....

[Btec]

i cheated. :hsugh:

wrd, this was a fun challenge, guys. time to sleep before work in the morning. later :thumb:

i think this is the right approach. this is the method im using.

i see what your saying, but your asking too many questions from im taking in. you said to ask one guard a question. but you cant get the a straight answer. your answering a riddle with another riddle. damn you confusing me. lol but i like your approach. :rock: on man

[AznJoe]

titties

[Beretta]

hes saying that u ask either guard which door would the other guard choose

the one telling the truth would tell u the one the liar would choose which is the wrong one - so you choose the opposite

if he asked the liar, he would still point towards the wrong one, hence you still chose the opposite

[tru_pimp]

yah id probably go to hell if i were in that situation.

[houstonman]

you ask them at the same time ... and i think i have a better one....tell them ..."excause me guards i have ONE question for the both of yall and this is it....can the both of yall walk into the doors behind yall and if u can do it"...the way i look at it is one question and sence you are the king why cant u order them to walk into the one they say thats the right one...at the end i think you'll see which one who is really lying

I think that would be considered two questions dude due to the 'and'. It's the king yea we know but that's not what the riddle was asking or stating.

[andrewK]

The real answer issssss

"What is the other guard going to say"

BEcause lets say

the doors are labeled one and 2.

the door 1 is the right door.

The truthful one will tell you that hte lying guard will say two
and the lying one will tell you the truthful guard will say it's two

That's one quesiton that only had to be asked to one guard

[tarantic]

Havn't seen Labyrinth, I'm gonna have to rent it this week http://www.houston-imports.com/forums/images/icons/icon14.gif What kinda movie is it?

YUP...this riddle can be asked many different ways, but that's the correct answer...you pretty much ask them what the liar would say and you'll get your answer...

[mister wiggles]

neither of the guards know which door leads to what. the king can ask 1 question, but the king can also open both doors. thats as far as i can think right now.
