I was going to come to your defence because I think Queen of Wands is being unfairly harsh...

But looking at that... that's some of the worst math and/or logic that I've seen in a long time.

Each man should pay 8.33.
How do you get that they end up paying more after being reimbursed?! If they each put in 10 and ended up with 1 back, how do you figure that any one of the paid 9.33?!
The nonsense of the original problem involves mixing addition and subtraction incorrectly, not division. It comes up with a nonsense result. You're applying double-nonsense to get the right answer the wrong way ("fudging").

If you want to do fractions, do this:
The men each paid 8.33 and 1/3c for the room, and .66 and 2/3c for the "gratuity".
The total paid is 27. 9 each.

There is no misdirection involving fractions, because the whole problem is set up to be done with physical, whole dollars.

I can't imagine what the +1 vote was for.



I changed my screen name to Divagating the Future from Queen of Wands.


The math was not mine..lol.."Eraserhead"→ I couldn't eat chicken for a year after seeing that movie!

The correct answer is, there isn't any answer. Read it again and you will see.

3 men enter a hotel while the hotel manager is away. They read that a room costs $30, so they leave $30 upon the desk,get the key and enter their room for a good night's sleep. Meanwhile the hotel manager comes back, sees the 30 dollars upon the desk, and tells the bell-boy that the room is no longer $30 dollars but now only $25. He then gives the bell-boy 5 single $1 dollar bills and instructs the bell-boy to refund the $5 to the men. Upon going to the men's room the bell-boy thinks; hmm?, "No way can 3 men evenly divide 5 $1 bills." So, he decides to "help" and pockets $2 for himself. He then knocks upon the men's door and gives them each $1.

Now here is the question. The men who each paid $10 for the room they thought was $30 but was only $25; each are refunded $1 by the bell-boy and 10$-1$=9$..and .. 3x9=27. So, there is now 27$ accounted for + the 2$ the bell-boy pocketed. But, $27$+2$ only = 29$..

What happened to the 1$..to account for the original $30....?



Now,the 3 men gave $30. The room was only $25. The manager gave the bell-hop $5 to refund the 3 men. The bell-hop only gave them back $3 stealing $2. So the 3 men got cheated and actually paid $27 instead of the correct $25.

I phrased the question to make it rhetorical. the 3x9=27 was a nonsensensicl operation to throw the reader off.

Oh!..I gave you the +1 because with the question about Joe,Rose,Harry,John, I asked for the 4 positions of each. I never told there was a dancer. I have ADD and I sometimes forget my ritalin dose. Likely this was such a time

No it wasn't. It was the calculation of the total spent.

And this amount spent went to two places. $25 to the hotel and $2 to the bell-boy.

I'd assumed they were photos of her??? Like a tag-line or signature; superfluous but not out of place.

I was informed in one of the staff sections that they are photos of a teen porn star, cropped to show just the head. Out of place here.

I didn't explain it well.

The misdirection is when it says that each guy paid $9 for the room, plus $2 tip. They don't. They pay a total of $25.00 (I shouldn't have messed with dividing this number among the 3 guys) plus the $2 tip, and the bellboy returns the remaining $3. There IS a real answer and it lies in the earlier misdirection.
When people fight to keep something as basic to human survival as healthcare a privilege, but insist the right to bear arms inviolate, we cease to move forward as a society. -- zapatos
