Logic Riddle - 08-25-03

Lets see who is smart enough to get this.

You are on planet run by computers. There are two types of computers. One type the TruthTellers always tell the truth. Another type the Liars always tell lies.

You meet 2 computer drones... Zak and Kaz. Zak says "Atleast one of us two is a liar".

Is Zak a liar or a truthteller? What about Kaz?

Explain how you know.

Zak is a truth drone and Kaz is a lying drone. If Zak was a liar, then saying at least one of them was a liar would be telling the truth and if Kaz was a truthteller then if Zak said at least on of them was lying it would be a lie...And if BOTH were liars neither would say that there was atleast ONE liar or else that would be the truth.

I think that's how it goes...

If zak was a liar then how would saying "atleast one of them was a liar" make that the truth?

no it wouldn't be a lie if atleast one of them actually was a liar.

Glar? Ok, if one of them is a liar, then saying 'atleast one of us is a liar' is the truth, isn't it? If Zak was a liar and Kaz a turthteller, he couldn't say that because it would be true. If Zak and Kaz were both truthtellers, then they couldn't say that because it was a lie and if Zak and Kaz were both liars saying that at least one of them is a liar is true as well, so they couldn't say it.

Hmm. He couldnt lie about at least one of them being a liar because that would be a contridiction. If he says that at least one of them is a liar and is telling the truth then Kaz is the liar.


Work is of two kinds: first, altering the position of matter at or near the earth's surface relatively to other such matter; second, telling other people to do so.

if the statement "Atleast one of us two is a liar" is the truth, then Zak must be a truth teller, and therefore Kaz is a liar.

A liar could not make that statement and have it be a lie.

good answers

If Zak is a liar then his statement is false. That would mean that it is false that there is atleast one liar and thus both zak and kaz must be truth tellers... but that would be impossible because we have already said that zak is a liar.

Therefore zak is a truthteller and his statement is true.

that makes kaz the liar.

Yay! I got it...I heard a similar one on Yugioh (don't stone me):

You're walking and there is a fork in the road. One path leads to the village of liars, the other to the village of truthtellers. The sign has been blown off, and you don't know the way. You meet a peasant walking from one of the paths. You may ask him one question in order to get to the village of the truthtellers. What will you ask?

What question should he ask to be able to choose the correct door?

I know this one...the answer is almost identical to my riddle.

Ask the guard what the other guard will say is the door to freedom.
If he lies and says the other guy(truth teller) will say it`s left then it`s right and vice versa.
If he tells the truth and says the lying man will say it`s the left then it`s the right and vice versa.


Work is of two kinds: first, altering the position of matter at or near the earth's surface relatively to other such matter; second, telling other people to do so.

Close. Ask the guard "If I asked the other guard which door was the one to freedom, which one would he point to?" No matter which one you asked, they would point to the door of slavery.
