Question: Two 5 year old boys stand on their balcony collecting rain. Boy 1 catches 2 cups of water whilst boy 2 catches 3. They see a smart looking man walking down the street. The boys make a bet to see who will get the man wetter. Boy 1 is 2 metres closer to the edge than boy 2 and the balcony is 25 metres from the street. Which boy will get the smart man wettest?
Answer: Neither because this man was smart so he carried an umbrella which blocked all of the boys water.
Question: There were 2 doors. Behind the 1 door, is hell and behind the other door, is heaven but you don't know which door will take you to heaven. In front of them, there were 2 brothers, which is guarding the door. One of the brother always lie and the other one always tell the truth. Of course you don't know who is lying and who is not. You only get 1 question to ask one of them to figure out which door leads to heaven. What question you might ask? Remember you only get to ask 1 question. it means that you can't ask one question each of them. that will be 2 questions. You only ask 1 question to any of them and no more. How do you do that?
Answer: Go up to one of the guy and ask this question, " Hello, which door that your brother will point if I ask him which way is the heaven." Then take the other door. Don't enter the door that he was pointing. This question will work for both of them because if you ask this question to the truth guy, he will point the hell because he knows that his brother will point hell and if you asked to the liar, he'll still point hell because he knows that his brother will point to heaven door, so he lied. That's why you take the other door.
