Re: CHRISTIANS

ok...when i brought htis up it was too make a fukin point...now i dont even remember wtf it was!! i shoulda known better...

You're damn right you should have known better!
Bringing math into a forum full of meatheads!! LOL!!

It really is in the presentation of the riddle as HP says - not so much the math.
As Dzone explained it the money the bellboy kept that we simply leave out and dismiss - to make it look like a dollar is missing.
When you present it though - it has to be 10 (what they originally paid) - 1 (which the bellboy gave back) = 9
Then take the 9 x 3 is where people hear the numbers and get messed up.


Ok - enough math for today.

Re: CHRISTIANS

jeez. They paid 9 dollars. Ya start with $30. Please somebody go to a math forum. or talk to a teacher. It's simple arithmetic. There is $30 total. Not 27. Not 28. Not 29. 30.

Re: CHRISTIANS

10x3=30
30-2=28
9x3=27
2+3=5
30-5=25
any way you work it, you get the correct answer. so long as you work the whole equation.

Re: CHRISTIANS

I hope I explained this right this time! LOL!

Numbers:
30-5=25

2 of the 5 taken
3 of the 5 given back

25+5=30

There's no other $1

Long version with full explanation:

The riddle:
Three men stay in a hotel and each pay $10 for their room. This makes a total of $30 ($10 x 3). But the hotel manager realises that the men have been overcharged by a total of $5, and asks the bellboy to refund this amount.

The bellhop thinks "$5 does not divide by 3 evenly, so I will keep $2 for myself as a tip, and refund $3, as this divides evenly in to $1 each" and does as such.

So each of the guests originally paid $10 (x 3 = $30). But they were refunded $1 each, so they have effectively paid $9 each. $9 x 3 = $27. Including the $2 the bellhop kept, this makes a total of $29.

So where did the other $1 go?


The solution:
There is, in fact, no "other $1". The net cost for the room is $25– the components of this are $25 (the originally paid price of $30 minus the refund of $5) plus the $2 "tip" the bellhop bestowed upon himself, plus the remaining $3 that are returned to them; $25 + $2 +$3 = $30, the original amount.

absolutely perfect! explained in the simplest form.

Thank you!

...awesome! I didn't read where you broke the riddle down as well. perfect. There's no disputing math. you rock! thank you.
