|Three men decided to split the cost of a hotel room.
The hotel manager gave them a price of $30. The men
split the bill evenly, each paying $10, and retired
to their room.
However, the manager realized that it was a Wednesday
night, which meant the hotel had a special: rooms
were only $25. He had overcharged them $5!
He promptly called the bellboy, gave him five one-dollar
bills and told him to return it to the men. When
the bellboy explained the situation to the men,
they were so pleased at the honesty of the establishment
that they promptly tipped the bellboy $2 of the
$5 he had returned and each kept $1 for himself.
The Problem: Each of the three men ended up paying
$9 (their original $10, minus $1 back) totalling
$27, plus $2 for the bellboy makes $29. Where did
the extra dollar go?
