Here's mine :
You have 2 US coins that equal 35 cents but one of the coins is not a dime. How do you get 35 cents?
Three travelling salesman share a hotel room for $30. After checking in, the manager tells the bellhop - "I forgot the room was on special for $25. Here's $5 to give them back." In the elevator, the bellhop doesn't know how to split $5 three ways, so he pockets $2, and gives each salesman $1. So each salesman paid $9. Three times nine is $27. Plus $2 in the bellhop's pocket is $29. Where's the other $1 ?
Two men were in a psychiatric facility and they decide, they don't like it there anymore. So they're going to escape. So they break out onto the roof and see the city stretching out before them. The first guy jumps across from one roof to the next with no problem. But the second guy, he's afraid of heights. So the first guy says "Don't worry. I'll shine my flashlight and you can walk across it to the other side."
The second guy says "No way, what do you think I am? Crazy? You'd just turn the light off halfway across and I'd fall to my death."
One of the coins isn't a dime..clever!
This riddle came from the MENSA book we used to play with as kids.
You are traveling through a country of people who are either green or red. All the green people must tell the truth, and all the red people always lie. You reach an intersection at dusk and want to know which way to turn to reach the nearest town. There is a man standing nearby, but it's almost dark and you can't tell what color he is.
What one question could you ask to get correct directions that wouldn't matter which color the man was?
