Problem:
A boy wants to go to Village A. In his search, he found 2 ways without indication. But he know one of the 2 ways leads to Village A, and the other leads to Village B, but he don't know exactly which way leads to which Village. The he met tow guys, and he knew that one guy is a liar and the other is honest, but also he didn't know who is the honest one of the tow guys. What he did is that : He chose by chance one of them and asked him a question Q, and then he followed the way indicated by this guy, which is the right way.

So what was the question Q he asked ?

I know these are wrong coz' they don't follow the instructions, but from these questions he'll at least know which one is the liar and which way to follow lol,
' Are you a liar?' or 'Does any of these lead to village A?'

Ok, now I wanna know the right answer. What is it?
 
I think it is that he asks one of them "Are you a liar?" and then ofcourse one replies, the liar will ofcourse le and the one speaking the truth will say the truth
 
I wish!

But in this case the honest one will say no and the liar would also say no. So you don't get to know which one lies. In addition, you need to ask more questions.
 
I will give the answer :

He wants to know the way to Village A ok. And he don't know who is a liar and who is not. So he will chose one of them by chance, and ask him this question :
Q : "hey ! if I asked the other guy : what is the way for the village B, what will he tell me ?". So the answer will necessarily be the right way of Village A.

Explanation:
if the honest person is asked, then he will tell him that the liar will give him the opposite way of village B, which is the Way of village A. And if it's the liar who is asked, then he will tell the opposite of what the honest person will say : the honest person can tell the true way of B, so the liar will lie about that and give the way of A .

So at the end whoever is asked, he will be forced to give the way of Village A.

Hope it's clear.
 
Yeah it is Jazakallahu Khayr for the explanation. . .

Ok next

If your sock drawer has 6 black socks, 4 brown socks, 8 white socks, and 2 tan socks, how many socks would you have to pull out in the dark to be sure you had a matching pair?

Five. There are only four colors, so five socks guarantee that two will be the same color.

it's a lie ?
wait !
If everything you tell is a lie , then the above sentence is a lie also, so you are telling a lie. But wait ! if your telling a lie, then that proposition is wrong, so I can't say that everything you tell is a lie (oh I have headache now !)
I think it's cyclic (a paradox), no logical answer can be found.

Its a lie. If its true then you are contradicting yourself.
 
^ lol you are correct

A lie. It can't be the truth without contradicting itself (and therefore being a lie), but some of my statements can be lies, and this is one of those statements.
Hope that cured your headache Indeed
and i apologise for causing a headache
