**5. Shortchanged Hotel Guests**

Three guests check into a hotel. They decide to share a room, which they are told will cost $30 for the night. Each guest pays $10 and they go up to their room. However, a short time later, the night manager realizes that she should have only charged them $25 for the room. She therefore gives 5 single dollar bills to the bellhop and tells him to refund the guests’ money. On the way up to the room, the bellhop reasons that there is no way for the three guests to split five dollars evenly, and they are not aware that they are owed a refund anyway, so the bellhop decides to keep $2 for himself, and simply tell the guests that they are each owed a refund of $1. And this he does.

Now, since the 3 guests each paid $10, but they each received a $1 refund, they each actually paid $9, and 9 times 3 equals $27. The bellhop kept $2, and 27 plus 2 is $29. But we started with $30. What happened to the extra dollar?

**6. The Unexpected Execution**

A prisoner has been sentenced to death. The king visits the prisoner’s cell on Saturday, and says, “Your execution will be carried out one day in the week that begins tomorrow. However, I will not tell you the day. In fact, I guarantee that it will be *unexpected*.”

The prisoner, preoccupied with his fate, tries to determine when the execution will happen. He reasons that it cannot be on Saturday, the last day of the week, because if the first six days have gone by without the execution taking place, then the prisoner will expect it to take place on Saturday, and the king stated that the execution will be unexpected. The prisoner then reasons that the execution cannot happen on Friday either. Since Saturday is an impossibility, that leaves only six possible days. However, if the first five days of the week have gone by with no execution, then the prisoner will expect it on Friday, and the execution is guaranteed to be unexpected. In this way, the prisoner rules out Thursday, Wednesday, Tuesday, Monday and Sunday, and happily concludes that he cannot actually be executed, because there is no way for the day of the execution to be unexpected.

How does the king manage to carry out the execution and still have it be unexpected?
