So, the other day, I had ten bucks in my pocket, and a friend asked to borrow a five. Well, then I had $5, and he had $5, and $5 - $5 = $0! All of my money dissappeared! Those mathematicians stole it from me! :mad:
The #9 is weird, because, for one thing, in any multiple of 9, the numbers in it will add up to nine or a multiple thereof: for example…in 81, 8 and 1 are 9…in 63, 6 and 3 add up to 9…in 25,191,546,381, those numbers add up to 45, a multiple of 9.
What’s so weird about that? The same thing is true for “3.” The “9” is just a special case of the “3” rule.
Er… 3 + 0 = 3. Good so far. 6 + 0 = 6. Well, maybe its an exception. 9 + 0 = 9. Er, 2 exceptions. 1 + 2 = 3. Well, that’s a gooder. 1 + 5 = 6. sighs
Maybe I misunderstood you?
It doesn’t matter, 'cause we’re doing a money trick.
Yes, you must have, if you’re talking about the post above yours. If a number’s digits are added up, and the sum is evenly divisible by 3, the number is divisble by three. The same is true for 9.
30: 3+0=3, evenly divisible by 3.
60: 6+0=6, evenly divisble by 3.
You can even extend it by adding the sum’s digits.
23985940303212: 2+3+9+8+5+9+4+0+3+0+3+2+1+2=51, 5+1=6, evenly divisble by 3.
The real question is why Monalisa9 reincarnated one of the most annoying types of threads on the board. Going to hunt some grys later?
I think this more recent thread may have prompted Monalisa9 to bump this old thread. Don’t know why the comment about the number 9 wasn’t just posted in the more recent thread, though.
Come to think of it, Monalisa9’s post about the number 9 came straight out of the left field - it seems to be completely unrelated to the thread topic. 
So anyway, what the heck happened to the missing dollar in the end? 
Harry S. Truman got it.
Here is the correct answer
You have to devide the cost of the room by 3 which gives you $8.3333333 apiece x 3 = 28 plus the 2 for the bell boy.
The extra dollar went towards paying for the hotel and was devided by 3 which is 33.33333.
I wished ANYthing in NYC could cost only $10…
Just in case anyone’s still wondering about this: the ‘riddle’ comes from the fact that 27+2 is a completely irrelevant figure. The cost of the room is 27-2, and the total money kicking around is 27-2+5, i.e. the cost of the room minus -5, the cost of the refund.
Mind you, given the events of 9/11, I must say that every character in this riddle is a hero.
:smack:
ooooh it was so cute…
the explanation was fine too
Prediction: this thread will still be alive in the year 2005.
Yeah, even though it has been answered correctly several times and incorrectly numerous times.
that is how forums work…
You mean that after a question has been correctly answered in GQ it is considered proper for people to continue answering it incorrectly? I’ll be darned.
no barbit
I meant people much too often do not read the whole thread … they just read the intro, the last few posts, and then they ask :
what is all that about here ???
The real riddle is where does one find a hotel dude that will refund $5.
Bah! Off-the-cuff explainations, algabraic equations, and in-depth analysis of this problem are for those with a dreadful lack of ambition. What I want to know is how I can incorporate the fundamentals of the missing dollar into my next money-making scheme.
