Tantor:
broccx answer assumes you know which person is the truth teller and which is the liar, if you knew which was which you would not have the problem in the first place. Also you have to ask each the same question.

it's actually the same question also, there is no need to know who the liar is in my solution.

Please read it again

Turns out it was the correct answer too!

You ask either one, "if I ask the other guy how to get home, what will he say?" The liar will tell you the wrong door, because he'd say the opposite of what the truth-teller would say. The truth-teller would also say the wrong door, because he knows the liar will lie. You'd only have to ask one of them one question, and you'd just have to know to go in the opposite door from the one they give you when asking them what the other would say.

So, i was right!

ahflirt23:


if you know which one is the truth guy from the beginning, then won't just asking him which way is the way home will solve your problem??

There is no need to know which is which in my solution, they'll both point in the same direction

Modenine for sure !!! have you guys heard him?! Flawless, elbow room

ask each of them what the other would say then, go the other way.


if "Road A" were the way home
and
"Road B" to Certain Death

ask the "Truth Guy": where would the "Liar Guy" point if I asked him the way home? "Truth Guy" would point to "ROAD B"

then

ask the "Liar Guy": where would the "Truth Guy" point if I asked him the way home? "Liar Guy" would point to "ROAD B"

both of them would point to the certain death road, you just go the other way. simple really.
