## hardest logic problem ever

Suppose you are in a land where orcs only tell lies, and elves only tell the truth. On your way to Gondor, you come across a fork in the path, going two seperate ways. One path leads you to Gondor, while the other leads you to some place else. There is also an orc and an elf standing around to answer any questions. Suppose you are allowed to ask just one question. What question do you ask to know that you take the correct path to Gondor?

 Ask the elf what the correct path is... Duh. I think it would be a lot more interesting if the orc and elf were indistinguishable.
 If they were indistinguishable, then you would merely ask: "And which way is the city you live in?" The answer would be the city of truth (or elves in this case). The lier would lie, thus saying the city of truth, the truther (pardon the made up word) would point to the city of truth.

If they were indistinguishable what would you ask the orc/elf?
 point to a road and ask if the other person would say if it was the road to gondor. This way if you are pointing to the correct road, and the person you are speaking to is the truth person, he would say no. Similiarily, if it was the lying person, then he would also say no. Thus you know to take that road. If the one you are pointing at is not the road, the truth person would say yes and the lying person would say yes as well. Thus you take the opposite road. And the third poster did not answer the question.
 In this problem is the person able to distinguish which is the orc and which is the elf??

 Quote by Mozart In this problem is the person able to distinguish which is the orc and which is the elf??
originally, yes.

But the answer to it is extremely easy, I don't see much hard logic in asking the truth-saying-creature about the truth-path-to-gondor.
 I agree with you.
 so if we edit the question n suppose that their are in distingush able. is muncleramos correct
 he is indeed.

 so if we edit the question n suppose that their are in distingush able. is muncleramos correct
It makes sense to me
 I hope my problem solving prof. never sees this post. I got a worse version on my final for my problem solving class, I am restating the problem, although not as eloquently: There are 3 types of people living on an island, who look exactly the same, Yohns, Wishi, and Naal. The Naal always lie, the Yohns always tell the truth and the Wishi always alternate between telling the truth and telling lies. You are trying to get to (Insert Town/Street/Destination Name Here), You may ask 3 questions, what are they? It's not the most DIFFICULT problem ever, but very interesting.
