broccx: 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.

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??

nuggard: This is a practical question I see no reason to even theorize it, I'll show my hands (both) to one of them and ask." do I have 5 fingers on each hand" if he says yes. then  he says the truth so I ask Liar which way is home, and go in the opposite direction.

liar on the other hand will obviously lie and say you have six fingers, so I go to truth and ask him the way home.

QED

In case you are interested in my theory it says establish the vera/vericity_spelling of the obvious and apply the rules of logical conclusion.

you can only ask 1 question.. not 2..

Lord_Reed: How is this a trick question or a riddle? If the truth gut tells the truth always then and the liar always lies then the simple question which way leads to death will get you home. How much IQ do you need for that?

Dig this riddle:

As I was going to St Ives
I met a man with seven wives
Each wife had seven sacks
Each sack had seven cats
Each cat had seven kits
Kits, cats, sacks, wives
How many were going to St Ives?

Lord Reed, sorry but you are wrong. If you ask the liar guy which way leads to death, he will point to the way which leads home. If you ask the truth guy, he will point the way which leads to death. They will point at different directions.

Answer to your question.. 1.. took me 1 sec..
