A man walks into a bar in, sets down two identical US bills on the counter, and makes an order. He asks for one rum, two margaritas, one vodka, two Pepsis, one lemonade, and three waters.
The bartender, who always gives change back in the minimum number of coins and bills possible, gives him two bills and one coin in change, then goes to prepare his drinks.
The man realizes that if he had paid the bartender with only one of any larger bill, he would not have received the same change. When the bartender returns, the man takes his drinks and leaves the bar.
The man returns home and decides to challenge his wife. He tells her what he ordered, how much it cost, and how much change he received. Then he gives her the following seven clues:
Finally, he asks his wife how much each drink cost him.
“Not only do I have an answer for you,” she tells him after working through his challenge, “but you gave me extraneous information.”
How much does each drink cost, and which clue does the wife not need to determine the cost of each drink?
Assume that margaritas, vodkas, and rums are the only alcoholic drinks; $1, $5, $10, $20, $50, and $100 bills are the only US bills; and 1, 5, 10, and 25 cent coins are the only US coins.
The Missing Dollar
Three friends check into a motel for the night and the clerk tells them the bill is $30, payable in advance. So, they each pay the clerk $10 and go to their room. A few minutes later, the clerk realizes he has made an error and overcharged the trio by $5. He asks the bellhop to return $5 to the 3 friends who had just checked in. The bellhop sees this as an opportunity to make $2 as he reasons that the three friends would have a tough time dividing $5 evenly among them; so he decides to tell them that the clerk made a mistake of only $3, giving a dollar back to each of the friends. He pockets the leftover $2 and goes home for the day! Now, each of the three friends gets a dollar back, thus they each paid $9 for the room which is a total of $27 for the night. We know the bellhop pocketed $2 and adding that to the $27, you get $29, not $30 which was originally spent. Where did the other dollar go?
