Chickens and Rabbits

There are several chickens and rabbits in a cage (with no other types of animals). There are 72 heads and 200 feet inside the cage. How many chickens are there, and how many rabbits?
Let c be the number of chickens, and r be the number of rabbits. r + c = 72 4r + 2c = 200 To solve the equations, we multiply the first by two, then subtract the second. 2r + 2c = 144 2r = 56 r = 28 c = 44 So there are 44 chickens and 28 rabbits in the cage.

Kicked off the train

A hobo had just been kicked off the train by one of the bosses. As he made his way down a dusty side road, he noticed a saffron robed man sitting next to a campfire apparently deep in thought. A wonderful smelling stew was bubbling in a pot next to him. It had been a full day since the hobo's last meal, so he went over to the man and tapped him on the shoulder. "I see by your robes that you are some kind of holy man," said the hobo. The Zen Master turned to the hobo and said, "You speak the truth." The hobo spoke, "I would sure like to try the stew you have on the campfire there; perhaps if I could tell you something to increase your wisdom, you will agree to share your meal." The Zen Master turned to the hobo and said, "Please, you are welcome to share my meal because you have already increased my wisdom!" What had the Zen Master learned from the hobo to increase his wisdom?
The Zen Master learned that he should find a more privace place to meditate if he doesn't want to be interrupted by every vagabond that happens by.

German/Swiss border

A woman who lived in Germany during World War II wanted to cross the German/Swiss border in order to escape Nazi pursuers. The bridge which she is to cross is a half mile across, over a large canyon. Every three minutes a guard comes out of his bunker and checks if anyone is on the bridge. If a person is caught trying to escape German side to the Swiss side they are shot. If caught crossing the other direction without papers they are sent back. She knows that it takes at least five minutes to cross the bridge, in which time the guard will see her crossing and shoot her. How does she get across?
She waits until the guard goes inside his hunt, and begins to walk across the bridge. She gets a little more than half way, turns around, and begins to walk toward the geman side once more. The guard comes out, sees that she has no papers, and sends her "back" to the swiss side.
