So we have all heard the classic riddle of being locked in a room with 2 doors and 2 people: one truthful guy and the other the is always the liar.
The one question you are allowed to ask is of course "Would the other guy tell me his door is correct"

NOW THAT IS NOT MY QUESTION!!!!
My teacher was telling us this riddle, and I thought I had this down, but he added a twist to it that I just cannot solve, so you guys have to help me!!!! Clues, answers, anything!

Riddle: You are in a room with two doors. One leads to death and the other leads to Escape/Freedom/whatever. There are two people. The truth teller must always tell the truth, and the liar can lie, BUT DOES NOT HAVE TO LIE!!!!! AND YOU DO NOT KNOW WHICH IS WHICH. You are only allowed one question to ONE person to get out.

The trouble is that the liar doesn't have to lie, so anyone out there, please give me the answer, or at least clues!

Every time I google this, the results always come up as 'The liar must ALWAYS lie"

Thanks

I would ask the truth teller to exit through the door of death. Then I'd go through the other one.

I would love to do that, but I think the question must be a definite Yes/No. Plus, you don't know which is which!

the soluion is: kill them both, eat their brains, and absorb all their thoughts.

or tell them both to go through different doors.

Don't ask them anything. Tell them to open their doors, and then you know. Since you still have a question left, ask who's the douche that out you in the room in the first place

Does the question have to have a yes or no answer? If so, could either of the people answer "Maybe"?

exit the door you entered through, you know that you weren't dead before you entered...
AND
if there are only two people in the room, you're one of them... must you always tell the truth? No. Then the other person, the not-you one, is the truth-teller, ask 'em anyway.

This may not be THE answer, but it is a RIGHT answer. Perhaps a broken answer....

Actually that is good.

Two people in a room, counting you.

Two doors, one to death the other to whatever. You entered through one door, obviously the whatever.

I think that's genius and the answer.

The teacher cannot dispute it.

It's like the riddle,

You're in a horrible car accident with your father(who dies) and the doctor says, "I can't operate on this person, he's my son, but your father's dead. Who's the doctor?"

UR Mom! (hee Hee hee)

:DEVIL:

I'd go with this.

BY PRIMUS, I THINK THAT IS THE ANSWER!!! Thanks!!! Of course YOU don't have to lie!! The Question is so freaking obvious!!! "Which is the door"!!!!!

*Jumps with joy like crazy* I have waited FOUR YEARS TO FIGURE THIS OUT!!!!!

Thu Sep 27, 2007 8:34 pm

Four years? Wow. I've driven students crazy with impossible puzzles before... but I usually get around to admitting they're impossible.

And it only took a few regular people and Leonardo to answer it for you! :grin:

Yup, but let's not get our hopes up! I will ask my teacher when I get the chance, so let's hope it's the right answer =D

OoO, let's hear one

Lot's of impossible riddles/puzzles have such simple or obvious answers, and when you figure it out, you feel like such an idiot for not noticing it :-B

Well done to Lorekeeper, I say.

Here is the impossible puzzle:

use a continuous line to intersect all segments of this diagram only once. The example fails because it cannot cross both remaining segments without crossing over already intersected segments.

Not-so-impossible riddles:

1) How is a raven like a writing desk?
2) What's the difference between a raven and a writing desk?
3) How many Frenchmen can't be wrong?

I guess nobody likes my riddles...

On your picture puzzle, are the segments the lines or the rectangular areas?

I think the answer to your first riddle is "Poe wrote on both". I'm thinking about the others (and about Lewis Carroll!). I presume questions 2 and 3 don't have obvious answers like "One's a bird, one's a piece of furniture," and so forth.

Good answer for number one. My answer was the more absurd "neither is an elephant."

Number two's answer is a flip-flop, "one a's b's, while the other b's a's"

Number 3 is from the Marx Brothers' Duck Soup.

How is a raven like a writing desk? 1- Poe wrote on both. 2-Both have qwills(of course this one became outdated with the invention of pens)
What is the difference between a raven and a writing desk? Poe wrote [/i]about ravens, not on them.

A house full, a hole full, but you cannot get a bowl full.

Just a note for the first question about he 2 doors. That can't be the answer. You don't know which of the 2 people can only tell the truth. You know that you can lie, hence you know which is which walking into the room. Though that was thinking outside of the box.

The riddle begins with "you are in a room," not "you enter a room."
If you are in a room and there are two people in the room, you are one of those two people. The riddle did not state that there were two other people in the room.

I get that. I was making a comment on the fact that if you don't know which person in the room always tells the truth ,then you can not be one of the 2 people because you know that you do not always tell the truth.
