There Nomads continue his trip to the summit of  Merapi Mount, after a 15-day journey finally found a village and stop by her into a stall.

Mother innkeeper         : Good afternoon sir
Traveler                        : Good afternoon bu, this village called what?
Mother                         : oh this village its name "Bengong Anom"
Traveler                        : I'm sorry bu, I will ask the way to the summit of Merapi is where?
Mom                            : (while approaching Traveler) Well sir, here it village with people are weird, so the master must be careful if asked. later on down the road (pointing) there are T-junction to the right and left, now that there is T-junction who always guarded by two elderly gentlemen. You wrote to ask gentlemen, my mother do not know right or to left.
Traveler                        : Hmmmm?
Mother                         : But you must remember the old fathers twins are very opposite.
Traveler                        : how do you know the opposite of its meaning?
Mother                         : Well sir, that if one of fathers say they are always honest.
And the other one bad man always lie. nah host later asked only to one of the gentlemen had been where the road to the summit .. what's left to right?
Mother                         : But be careful sir .. There should be masters know and remember .. that these two gentlemen would not be questioned all, only one & only be answered once (one question). because if they'd asked 2 x angry.
Traveler                        : sorry mam, mother did not know where the father is honest and a liar?
Mom                            : Wow sir, the people here in the village no one knew, including me, excuse me?
Traveler                        : Well I will try to ask one of the gentlemen who at that junction. just one question?
thanks (as he said goodbye)
Mother: master caution!

Well, now the question for you what must be submitted by the traveler, for the once asked his father who at one junction, the answer would be to make the traveler knows the direction to the top of the mountain is right? question is how?

The Answer
Here we are not going to give an answer, but there is little to add, this puzzle we wear Mathematical Logic, which it uses Negation more precisely, what is a Negation, Consider the following:

Negation (denial) is a statement that there is not statement by giving the opposite of that statement.
For example:
Ants bigger than elephants
The sentence above is false, using negation we can turn it into a sentence correctly, such as: Ants are not bigger than elephants

Well, that's for a quick introduction.
now for this puzzle. we both use the Application of Negation. So tuk wanderer later, because it allowed only asked once and only allowed to one father, travelers can ask questions like this:

Traveler: Sir, If I asked the father of twins where the mountain is right, about what he would answer?

Surely the answer is: If the answer is the answer to the true left to right (Negation), and vice versa.

Logically:
1. if we ask the handyman to lie, he knew his brother would tell the truth the way to trim to the right, but because he is liar so say to the left ....
2. if we ask an honest father, he knew his brother would tell a lie your way to trim the right mountain his brother will say to the left, then left saying he would also

Upshot: we live to Negation answer any answer or take the opposite of the statement of the old man answers. How? it's easy? Hopefully Helpful
