Does anyone know the puzzle of the missing dollar. I've known of this puzzle since I was a teenager and still don't get it. Each step seem logical but the conclusion is illogical.
Here's the puzzle. Three men go to a hotel to get three rooms. The desk clerk says each room is 10 dollars (this must be a very old puzzle).The three men pay the 10 dollars.
Later on, the desk clerk realizes he should have only charge the three men a total of 25 dollars. He call the bell boy, gives him five dollars, and tells him to return it to the three men.
The bell boy, a little crocked, thinks: I just return to each one of the men a dollar, and I'll keep two dollars for myself.
Now, if he returns one dollar to each of the three men, the rooms only cost nine dollars each, Thus, three times nine = 27 dollars. The bell boy kept two dollars which equals 29 dollars 27 plus 2), where did the other dollar go?
