If that means any guard will tell only lies or only truth, then

If I were to ask you path to the city, which path would you indicate?

should work

Following your freedom from the prison you have landed in the city...

You have again been convicted and found guilty of an abominably horrendous crime. However, you have been at your best behavior so the warden decides to give you a chance at freedom. You've been brought into a hut in the forest with the warden. You have to pick the path to your freedom (the city) or you will follow a path that leads back to the shack where you will be tied completely so you cannot be moved and left. Once more, there are a few conditions:

1) It will be solved by either chance or intellect.

2) This time you're in a straightjacket and your legs are chained together so that you cannot make any large strides.

3) You may ask only one guard one question.

4) There are seven paths, each guarded by 2 guards.

5) The guards will either tell the truth or lie when asked.

6) The warden is behind you.

7) Once you have chosen a path, you must take it.

That DOESN'T mean the guard will only tell lies or truth, so you could still get a bad answer.

well if the guards can lie or be truthfull at will, it wouldnt serve to ask any questions as no information recieved can be determined as usefull. i would start gnawing straps.

well i take that back, you can ask one question, and theres a 50% chance of it being incorrect. take a chance i guess and point to a trail (with your nose or foot), and ask how many to the left or right is the trail to freedom. u got a 50% chance of him lying or you making it to freedom. i dont see any possibility of getting a 100% factual answer.

maybe you could argue that since they all work for the same prison, they are all equal which means they are 1 in the same and are all subject to answering your question since they are all "the guard". ask which trail is the correct one and take the majority vote.

or maybe you could ask a guard "if your a liar point to the trail to freedom, if you are truthfull, point to the trail to freedom."

heads i win, tails you lose.

"Which of these paths do not lead to freedom (the city)?"

A truthful guard would point to the 6 incorrect paths. A lying guard would (hopefully, if my logic is correct) point only to the freedom path.

Liar points to correct path, the other will point to 6 wrong paths.

Which paths will the truthful guard tell me to take?

Truthful guard points to correct path, the other will point to 6 wrong paths.

If the guard tells the truth and answers yes, then this is still not the path to freedom because the one he asked is the liar and will say yes.

On the other hand, if the liar guard say no, then this is the path to freedom because the other guard will be telling the truth, which will be yes, and being a liar, he will say no.

A guard could just as easily point to any set of random paths, including both the city and shack path. They'd still be lying.

Also as stated "That DOESN'T mean the guard will only tell lies or truth"

Or

Since all this happens in a 'forest' and not a cave, you can just choose any path go outside, explore alittle, wander off the paths until you get to the city.

How many questions can I ask the warden?

"If you ask guard#2

and he asks guard#3

and he asks guard#4

and he asks guard#5

and he asks guard#6

and he asks guard#7

and he asks guard#8

and he asks guard#9

and he asks guard#10

and he asks guard#11

and he asks guard#12

and he asks guard#13

and he asks guard#14 'If I were to ask you path to the city, which path would you indicate? '"

So you take the path he points out.

"if this question is olny worth 40 points, then why do i care which is the path to freedom?"

How about "Would you accept a bribe?"

1) there are 7 paths, each guarded by 2 guards.

2)He didn't say 7 consecutive paths.

---thus there being 7 paths in front of you, 14 guards, and only 1 question.

with 7 paths, 1 leading to the city, and 1 leading to the shack. where do the other 5 lead?

as far as climbing a tree.. you're in a stray jacket. Good luck monkey!

either that or just decide not to go down a pathand just make your own path either way you will get to the city AKA freedom

CF101

"Would the other guard tell me that this is the right way?"

If you have asked the truthful guard, then the answer would be that it is the wrong way.

If you asked the lying guard, then the answer would still be that it is the wrong way.

Hence, you know now that the otehr way will always be teh right way...

(damn I'm good)

:-)

Ah, but what if the paths cross? That's outside the bounds of this riddle -- if a left path crosses a left path, it doesn't matter, if a right path crosses a right path, it doesn't matter, if a left path crosses a right path, then you have a path taht can lead EITHER to good or bad, and the riddle states that each path leads either to freedom or to the shack, and a path that "splits" into the two opposing directions would thus break the rules.

The chains and straightjacket are completely irrelevant.

The two guards guarding are irrelevant, unless the riddle is misstated, and means to say that of each pair, one is a pathological liar, while the other is completely honest.

The warden being behind is also irrelevant.

The choose and stay the course rule is also irrelevant -- once I have asked my one question, I must know my answer. Well, I suppose it codl be to rule out the posibility of my coming toward the end, seeing the shack, running back, and choosing again.

And of course, the whole question is irrelevant, because you would never see me commit a horrendous crime.

One more alternative answer is that, you choose any path, go outside the hut, block all the 7 doors and set fire to the hut, then you can take your own sweet time to get away to the city.

Or, go outside, get to a payphone, call up a good friend or relative to get them to come untie you later, go back, get tied up, left behind, and wait for the person you called to come help you.

Actually, to reiterate my answer earlier that since there are seven paths only, 6 of them leads back to the hut, which means that,

path 1 goes back to path 6

path 2 goes back to path 5

path 3 goes back to path 4

or some other combination, which means the only path left must be the path that you came to the hut from.

then just go onto google satellite maps and zoom in till you find the right path

The Warden isn't a guard.

"A" does not translate into "one."

Lets pretend you took a bad path, so it's a path that leads to the city.

Lets pretend you didn't take that path and took another path, but that's also a path that leads to the city.

Does this explain how "a" does not necessarily mean "one"?

The straightjacket is so that people refrain from comments about beating up the guards, etc.

Also, do not make any assumptions such as being able to see the path before you leave the shack and have chosen it.

You have until next the 29th to solve the riddle..

> "What path leads to the city if you are telling the truth, and back to the shack if you are

> telling a lie?"

That's really two different questions, isn't it?

- qwaletee

Wouldn't that be a good path?

Drew

So, if he answers truthfully, he will say which one path he would lie about being wrong, ie. the right path.

On the other hand, if he lies, he will say which one path he would lie about being wrong again - because he'd be lying about the "opposite veracity".

"If you were to respond with a lie, which is the one path that you would not indicate as being the correct path?"

or a false answer to

"If you were to respond with the truth, which is the one path that you would not indicate as being the correct path?"

But if one were to respond with the truth, there would be more than one path that one would not indicate as being the correct path.

Equivalently:

"If you were to respond with the same veracity to that which you are prepared to answer me now, which is the one path that you would indicate as being the correct path?"

Instead:

"What is a path which, if you were to respond with the same veracity to that which you are prepared to answer me now, you would indicate as being a correct path?"

Ask either guard:

"The warden wants to take me the correct way. Is that OK?"

I still stick by my original post, that you could ask:

"Would the other guard tell me that this is the right way?"

Asking if the warden wanting you to take the correct way will not have them say "go there."

Confusing, you have succeeded in proving your namesake; however, the guard can choose to lie for one section and tell the truth for the other.

Drewk, good point. I meant the hut though.

I asked to have the points refunded because nobody succeeded.

The answer is: "The question doesnt matter. Just pick the same path you took from the city to the hut to get to the city."

http:Q_21446978.html

Otherwise, either of my two questions would work assuming the guard must either tell the truth or lie
