You walk up to a mountain that has two paths. One leads to the other side of the mountain, and the other will get you lost forever. Two twins know the path that leads to the other side. You can ask them only one question. Except! One lies and one tells the truth, and you don't know which is which. So, What do you ask?

You ask each twin What would your brother say?. This works because... Well, let's say the correct path is on the left side. So say you asked the liar "What would your brother say?" Well, the liar would know his brother was honest and he would say the left side, but since the liar lies, he would say right. If you asked the honest twin the same question, he would say right, because he knows his brother will lie. Therefore, you would know that the correct path was the left!

Jordan is leaving from a small town in Wyoming and hiking through the wilderness to a post where he will spend the summer. The hike will take Jordan six days. One man can only carry enough food and water for four days. Jordan cannot take a mule or any other animal to haul his food and water, because there will be insufficient food and supplies for the animals at his destination.

How can Jordan make it to his destination?

Jordan takes two other hikers with him. Each hiker starts out with a four day supply of food and water. After the first day, the first hiker gives a one day supply to each Jordan and the second hiker. This leaves the first hiker with a one day supply to go home and Jordan and the second hiker now each have a four day supply again. After the second day, the second hiker gives Jordan a one day supply and keep a two day supply for himself so that he can get home. This gives Jordan a four day supply of food and water, and now he has enough to reach his destination.

Four members of a band are walking to a night concert. They decide to take a shortcut, but must cross a bridge. Luckily they have one flashlight. Because of the varying size of their instruments, it takes each member a different amount of time to cross the bridge - it takes the first person one minute, the second person two minutes, the third person five minutes and the fourth person ten minutes. They must cross the bridge in pairs, travelling at the slower speed so if the one minute person went with the ten minute person, it would take a total of ten minutes. Since there is only one flashlight, one person must come back across the bridge, then another pair can cross. They only have 17 minutes to cross the bridge and still get to the concert on time. What order should they cross to get everyone across and get to the concert?

First, the one minute person and the two minute person must cross the bridge, for a total of two minutes. Then the one minute person should come back with flashlight - total of three minutes. The five minute person and the ten minute person cross together next, making the total thirteen minutes. Now the two minute person goes back and (total now fifteen minutes) and gets the one minute person and they cross together bringing the total to seventeen minutes.
