3 friends go into a motel. the man behind the desk said the room is
�30, so each man paid �10 and went to the room.
a while later the man behind the desk realized the room was only �25,
so he sent the bellboy to the 3 guys' room with �5. on the way the
bellboy couldn't figure out how to split �5 evenly between 3 men, so he
gave each man a �1 and kept the other �2 for himself.
this meant that the 3 men each paid �9 for the room, which is a total
of �27; add the �2 that the bellboy kept = �29. where is the other
pound?
i've seen this kind of thing before, but can't remember the solution. anyone know?
