- A man is on a trip with a fox, goose, and a sack of corn. He comes upon a stream, which he has to cross, and finds a tiny boat which he can use.

It is not possible for him to leave the fox alone with the goose, or the goose alone with the corn. How can he get all safely over the stream?
Show Answer
Answer: He will take the goose over first and come back. Then he will take the fox, and bring the goose back from the other side. On his next trip, he will take the corn and come back alone to get the goose. Finally, he will take the goose over and the job is done!
- You are standing in front of a room with 1 light bulb inside. You cannot see if it is on or off. Outside the room there are 3 switches in off position. You have to find out which switch controls the light bulb inside, but you get to enter the room only once. So how do you find out?
Show Answer
Answer: You turn 2 switches on and leave 1 switch off and wait about a minute. Then enter the room, but just before you enter, turn one switch from on to off. Once in the room, feel the light bulb - if it is warm, but off, it has to be the last switch you turned off. If it is on, it has to be the switch left on. If it is cold and is off, it has to be the switch you left in the off position.

How did the man win the bet?
Show Answer
Answer: The man did exactly as he said he would and wrote 'your exact weight' on the paper.
