Y’all are quite good at these brainteasers!  Ashley T., eddy, Alyssa, Ruben, and Paola all came up with the right answer AND some tasty dishes for last week’s brainteaser.  Whoohoo!

I visited Philadelphia yesterday with a couple good friends to see the Magic Gardens, which – if you’re ever in Philly – you absolutely HAVE to go see.  Forget the Liberty Bell and the Rocky steps.  If you want your breath taken away, go see the Magic Gardens.  Preferably on a sunny day.  I almost didn’t include photos because photos – no matter how good – cannot do this place justice.  Isaiah has lived and worked in this building for about 20 years, and he’s covered almost every inch of it with his mosaics.  Go.  You won’t be disappointed.  (There’s a documentary about him called In a Dream playing in some cities now.  That’s why we visited – to see the art before we watched the movie.)  I really, really enjoyed this place.  And Isaiah is such a generous man.  He was working on some pieces when we visited and asked us to help him, and he showed us how he made some of his art.  A very sweet man.

Anyway, hanging out with my friends reminded of the following brainteaser because a mutual friend of ours told us this one a long time ago.  It has nothing to do with Philadelphia, or mosaics, or gardens.  My mind works in mysterious ways.

Three men go to a hotel to rent a room.  The clerk says the room will cost $30.  The three men decide to split the cost evenly, pay $10 each, and go up to their room.  Later, the manager informs the clerk that the room was actually $25, not $30.  So the clerk gives the bellboy five $1 bills to return to the three men.  On his way to their room, the bellboy realizes that he cannot divide $5 equally among the three men, so he keeps $2 (bad bellboy!) and gives the men $3 ($1 each).

Since the three men each paid $10 (for the $30 room), and they each got $1 back, each man really paid only $9.  So altogether, the three men paid $27 for the room, not $30 because 3 x $9 = $27.  The bellboy has $2, so that makes $29 so far ($27 + $2 = $29).  But the three men paid $30 at the beginning.  So where is the other dollar?

I think I got it, don’t read my post if you want to try for yourself.

So the three men paid $27. The bellboy got $2 but that doesn’t make $29. Since the room costs $25, the $27 that the men payed was split, $25 went to the clerk for the room and the remaining $2 went to the bellboy. Now you might be wondering why this doesn’t add up to $30. That’s because the men each got $1 back, so they got $3 in total. This, together with the $25 they payed for the room and the $2 the bellboy took makes $30. Phew!

WOW! Way too much math for me to even attempt to figure this one out. Math makes my brain hurt :(

If I’m not wrong, like what the first comment says, basically the 3 men paid $27 – $25 of it went to pay for the room, and $2 went to the bellboy. Ta-dah!

The misleading part of the question is where it says “The bellboy has $2, so that makes $29 so far”. What the bellboy gets should be SUBTRACTED from what the men paid.. not added to it! Since that money comes out of what the men paid.

Hope it made sense!

mmm… well since the the price of the room was switched from $30 to $25 so you really can’t use the $30 any more in the math so if you use the $25 figure instead. The bellboy kept $2 for himself. The men paid $27. $27 – $2 = $25 which is the new price of the room. The men overpaid by $2 due to the bellboy’s keeping it. And since they got 3 dollars back making it $30 bucks. There is not one dollar missing well just $2 coz of the bellboy.

The math is backwards; the hotel kept $25, the bellboy kept $2, and the men kept $3. Add them all up and you have $30 in the hands of the various parties. Or, if you want to insist on backwards math; the $30 the men gave became $27 (and they kept $3), of that $27, the bellboy kept $2, and the hotel kept $25. Similarly, we started with $30 spent, the roomy’s have $3 back for beer, and the bellboy has $2 for a shot of whiskey! If you still aren’t satisfied that all of the money is accounted for, then you can give me the $1! LOL! :-)
