$$ Solve This Puzzle

3 men go into a hotel.
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?

    Kat,

    The 3 men after the $5 refund had paid $25 for the room.
    $25/3 = $8.333333 + $1 = $9.333333 * 3 = $28 + $2 = $30

    Hi Duc,
    it took me about 1.5 minutes to figure out they paid $9.33 each, not $9 but I thought it was pretty funny that a lot of people couldn’t solve it. Tested them over the weekend. Granted, there was alcohol involved at the party but still…

    Kat,

    A good example of “anchoring” which is very common, it is a heuristic after all.
