In this video, Jeff Altman, The Big Game Hunter explains how to answer another of those tricky brainteaser questions that hedge funds use — this one has two guards, One lies and one tells the truth and one question that you can ask. What is that question? Yep it makes a lot more than I do

Summary

Today I want to offer up another 1 of those "wonderful" hedge fund questions. There are different nicknames for this one, but I'm going to call it, "the truth teller and the liar."

Here's the scenario. You walking down the hallway and see 2 doors with one guard in front of each door. The they both know the correct answer, but one always gives the correct answer and the other one always lies. You only have one question that you can ask. Who do you ask and how do you choose?

Remember, only one question.

Here's how to answer the question. The short version is, whatever answer you get, choose the opposite one. The reason for it is simple.

Here's the answer the question one. Again, you choosing the opposite of what you were told. The question that you have to ask is, "if I ask the other guard which door to open, what would he tell me?" That's the question you want to pose in order to figure out the answer.

If you ask the honest guard about what the other one would say, he knows that the guy is going to lie. The liar would tell you to go to the wrong door. Right? If you ask the longer the question, he is going to lie to you.. He is going to tell you the wrong answer.

No matter what, you have to go to the opposite door of what you are told.

  4. A variation I like to take on the riddle. There are two doors, one going to
    a good, happy place, the other going to some terrible place, but only one
    guard. You know that this guard either always tells the truth or always
    lies, but you don’t know which of these is true. Can you guarantee you go
    through that door to a good, happy place by asking the guard a single
    question? If so, what question do you ask?

    The answer is that, yes, you can guarantee that you go through the door to
    a good, happy place simply by asking the guard “Which way would you say I
    should go to get to the good, happy place?” A person who always speaks true
    tells the truth about the way you should go. The liar has to lie about what
    he would say, which would cause him to tell you the same answer as the
    person who always speaks the truth.
