Let's do some lateral thinking (though logic puzzles themselves are awesome too).
1. How many times can you subtract the number 2 from the number 32?
2. The rope ladder of a boat hangs over the side of the boat and just reaches the water. Its rungs are 8 inches apart. How many rungs will be under the water when the tide rises 4 feet?
3. How much dirt is in a round hole that is 9 feet deep with a diameter of 3 feet?
4.Train A and train B are crossing the country, from coast to coast, over 3,000 miles of railroad track. Train A is going from east to west at 80 miles per hour, and Train B is going from west to east at 90 miles per hour. Which train will be closer to the west coast when they meet?
5. A truck-driver was turning left into a one-way street the wrong way. Halfway down, he was seen by a policeman, who made no attempt to stop him. Why?
And if anyone really really really wants a challenge, do this:
