The torch cannot be thrown across the bridge. Instead, someone must walk it back to the other side. Each band member walks at a different speed. If two members cross at the same time, both must walk at the speed of the slower band member. Bono takes 1 minute to cross. Edge takes 2 minutes to cross. Adam takes 5 minutes to cross.

Brain Teasers - Motel

Solved 8.5k times
Brain Teasers - Motel Motel Situation: Three friends check into a motel for the night. The clerk tells them the bill is $30, payable in advance. They each pay the clerk $10 and go to their room. A few minutes later, the clerk realizes he has made an error and overcharged the trio by $5. He asks the bellhop to return $5 to the 3 friends who had just checked in. The bellhop sees this as an opportunity to make $2 as he reasons that the three friends would have a tough time dividing $5 evenly among them; so he decides to tell them that the clerk made a mistake of only $3, giving a dollar back to each of the friends. He pockets the leftover $2 and goes home for the day! Question:  Now, each of the three friends gets a dollar back, thus they each paid $9 for the room which is a total of $27 for the night. We know the bellhop pocketed $2 and adding that to the $27, you get $29, not $30 that was originally spent. Where did the other dollar go? Murder Situation: The midnight train is coming down the mountains. Art Farnanski seems to be sleeping in his seat. At the station, all the passengers get off the train except one.

Hours later the four people that had shared the train compartment with the dead man are at the police station. The man in the dark suit: "I'm innocent. The blonde woman was talking to Farnanski." The blonde woman: "I'm innocent. I did not speak to Farnanski." The man in the light suit: "I'm innocent. The brunette woman killed him." The brunette woman: "I'm innocent. One of the men killed him." Question: The police detective comes up to you and says: “I know that four statements are wrong and four are true. Who killed Farnanski? (Only one person is guilty).” Trees Statement: You have 10 trees and you have to plant them in five rows, but each row must contain 4 trees. Question: How is this possible?

Brain Teasers - Lethal Duel

Solved 5.9k times
Brain Teasers - Lethal Duel Duel Situation: Three men, Adam, Bertie and Charlie, agree to take part in a lethal three-way duel. They each have a pistol and several rounds of ammo, and they draw lots to see who will shoot first and who second. Then they stand an equal distance apart, and they take turns to fire. When it is a player's turn, he can take one shot at any target of his choice. Then, the turn passes to the next player. The duel continues until only one player is left alive. For simplicity, we can ignore the possibility of a player becoming injured and unable to shoot: a player is either alive or dead. We also assume that each player chooses to play in such a way as to give himself the best chance of winning. Now Adam and Bertie are crack shots and will always get a kill, but Charlie is only a moderate shot and will only get a kill two thirds of the time. All three men know this. Question: Of the three men, who has the best chance of winning the duel? Murder Situation: A man was found murdered on Sunday morning. His wife immediately called the police. The police questioned the wife and staff and got these alibis: The Wife said she was sleeping. The Cook was cooking breakfast. The Gardener was picking vegetables. The Maid was getting the mail. The Butler was cleaning the closet. Question: The police instantly arrested the murderer. Who did it and how did they know? Boxes Situation: Three closed boxes have either white marbles, black marbles or both, and they are labeled white, black and both. However, you're told that each of the labels is wrong. You may reach into one of the boxes and pull out only one marble. Question: Which box should you remove a marble from to determine the contents of all three boxes?
