Here is one for you:
3 men stay at a motel. The front desk charges them $30.00 for a room. They split the cost $10 each. Later the manager tells the desk man that he overcharged them, the cost should have been $25. The manager gives the bellboy $5 and tells him to give it to the men. The bellboy cheats the men and pockets $2, giving each of them only one dollar. Now each man has paid $9 to stay in the room. 3 x $9 = $27. The bellboy pocketed $2. $27 + $2 = $29 - so where is the missing dollar?
Heck I can't even hardly figure out Laughing Terry's puzzles what makes you think I can figure this one out.
