英语和数学都比较烂。同事听来的这则小故事着实把俺给难住了。

故事的标题是：This will mess with your head ! What's is your answer?


3 MEN 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 DOLLAR?
