Here are some logic problems that you can try cracking! Don't have a second thought about emailing me for the answers!!!


Problem #1
A man goes to work in the morning. He rides the elevator to the 12th floor, gets off the elevator and takes the stairs to the 20th floor where he works. When he gets off of work at 5:00 he gets on the elevator and rides it all the way down. Why does he take the stairs on the way up and the elevator on the way down?


Problem #2
Three people check into a hotel. They pay $30 to the manager and go to their room. The manager finds out that the room rate is $25 and gives $5 to the bellboy to return. On the way to the room the bellboy reasons that $5 would be difficult to share among three people so he pockets $2 and gives $1 to each person. Now each person paid $10 and got back $1. So they paid $9 each, totalling $27. The bellboy has $2, totalling $29. Where is the remaining dollar?


Problem #3
What moves on 4 in the morning, moves on 2 in the afternoon, and moves on 3 in the evening/night?


Problem #4
A plane is going from the United States to Canada. It crashes right on the middle of the border. Where do you bury the survivors?


Problem #5
There are two fathers and two sons on a boat. Each person caught one fish. None of the fish were thrown back. Three fish were caught. How is it possible?
