Barclays Capital Interview Question
AnalystsCountry: India
Interview Type: In-Person
Let's forget about the answers to the question and think about all possible combinations.
T represents Truth person, L represents Lie person.
3rd person 2nd person 1st person
TTT
TTL
TLT
TLL
LLL
LLT
LTL
LTT
based on the answers, I eliminated all but two combinations TLT and LTL.
Then eliminated LTL because if 3rd person is lying, then first person has to be telling the truth since 3rd person is objecting to the answer of 2rd person(first person is liar).
So the answer is Truth.
As Anonymous said below, this doesn't make sense to me. If the third person is lying, then the second person is telling the truth. The second person says that the first person is lying. So LTL is valid, there is no contradiction that I can see.
If the third person is telling the truth, then the second person is lying. The second person says that the first person is lying, so the first person must be telling the truth. So TLT also seems valid.
With the problem given I don't think there is a definite answer for the third person. If there is supposed to be a correct answer then we must be missing some information.
I think the Question is not complete here. If we just rephrase the question to following then we can easily eliminate LTL.
You ask the first person 'To which Tribe do you belong to?' and he answers in his native language which you don't know. The second person says that the 1st person belongs to the Lie Tribe. And the thrid says that the 2nd person is lying (in english).
I think the third guy belongs to the "lie" speaking tribe.
How? ... because the first person replied in native language which means he understood the question in English but pretended as if he didn't speak English. So the first person was lying, which implies that third person was lying too.
I don't think you can eliminate LTL from below
"Then eliminated LTL because if 3rd person is lying, then first person has to be telling the truth since 3rd person is objecting to the answer of 2rd person(first person is liar). "
The second person is objecting rightfully to the first persons answer given he is telling the truth. The third person being from the lying tribe is accordingly opposing the truth as told by the second person.
There are two possibilities TLT and LTL. To explain In plain english, 3rd person could be supporting 1st person either in his lie or in the truth, 2nd person is always speaking exactly opposite of first person is saying hence TLT and LTL. This question is incomplete, we need some more details to give a concrete answer.
Third person belongs to same tribe as first person....
