Day three guests to stay at a hotel, hotel boss said: One night accommodation, each guest at 10 yuan money. Thus, the boss gave each guest 10 yuan, then the boss has to charge 30 yuan. Later, the boss saw that today is a hotel in concessions, 3 personal charge will be 25 yuan, so he called Partner, asking him to take the money back to five yuan guests. Waiters would like to go on the road: guests do not know how much their boss also, I know that corruption is dead people. Therefore, the waiter took two yuan sneaked into their own pockets, each one yuan back to the guests. In this way, each show guests have 10 yuan, and now also has one yuan per person on the show each equivalent to nine yuan. This subject, there is no doubt that all guests take money out corruption + waiters money, it should be all the money. That problem has come, and guests each show nine yuan, which is 27 equivalent to 3 times 9, coupled with corruption waiters two yuan, a total of 29 yuan, 30 yuan is a total original. The swap of one yuan less where to? !
