Look,
Start
1st 10
2nd 10
3rd 10
Payed for hotel
1st/2nd/3rd 0
Hotel 30
Bellhop is sent back
1st/2nd/3rd 0
Hotel 25
Bellhop 5
Bellhop takes two, and gives the guys back 1 each
1st 1
2nd 1
3rd 1
Hotel 25
Belhop 2
1 + 1 + 1 + 25 + 2 = 30
That is what you want
The rest was just bad logic
Look at 3 x 9

well, 3 x 9 = 27
and that plus the 2 the bellhop took makes 29
the question is, what happened to the last zenny?
they ended up having three back, while the bellhop kept 2
the thing is, The 2 that the bellhop kept is part of the cost!!!!
Therefore,

is pretty much right
I just hope that this post stops all the confusion |

I think you don't have to obtain a total of 30, but 25.
Each guy spent 9z, = 27z spent in total ; but they should get back more money, so they spent more than they should.
I believe the right formula is 9 x 3 - 2 = 25 |

This might be a bit old of a thread but i got the answer for it. If they each started off paying 30 that means they each payed 10.
1st. 10
2nd. 10
3rd. 10
once the clerk realized he overcharged he gave the bellhop 5 back to give to the people, the bellhop relaized he couldn't divide it evenly so he took 2 and gave the guys each one back.
1st. 9
2nd. 9
3rd. 9
bellhop. 2
If you stopped there you would get a total of 29. The question isn't asking where the other zenny wen't but rather how much they got back, they started with 30, got 5 back, then each of the 3 guys got 1 back and the bellhop kept 2. (10 + 10 + 10 = 30... 30 - 5 = 25... 25 + 1 + 1 + 1 + 2 = 30) Your problem in this question is the fact that you are subtracting and then multiplying afterwords, you need to use only subtraction and addition because the multiplication messes it up. What they payed from what they got back which causes a misshap in the ammount of money they recieved.
If that dosen't explain it to how much you want i will go into more depth about it. |

dracoon is right in the way he add it up if you multiply you end up confuseing your self as you did. |

This thread should be long gone, but this is pretty much the answer. It is a math riddle, but more of a logic question. If you'd look at me talking to Dracoon, you would have seen me say No Fractions. Sorry, but you are wrong FFDude. |

Its simple.See,like you said,it makes you think they paid nine each.whereas they ACTUALLY spent 25 altogether.if they spent nine each then the multiplactation and adding would throw the answer off because they DIDNT REALLY SPEND NINE EACH
Instead, the actually spent 9.1/3 each, which adds the missing one.
1/3 X 3 = 1
9 X 3= 27
27 + 1 + 2 = 30
The puzzle makes you think they spent only 9,but they really spent 9 1/3.
Have you gone through algebra yet?Its simple math,and you dont even need to know algebra. You are looking at the puzzle from the wrong angle, which creates a paradox that they really paid an extra 1/3 but not easily figurable. the fact of the matter is that you are making the puzzle too complicating with multiplying. But if you do it backwards
30-5=25
25+3+2=30
And all this came from a twelve yr old oO |

OK, I have this exact question in a logic book and here is the answer...
The math u r performing isn't right... They didn't pay 9 each, they should have payed 25 altrogether, but the 3 they got back plus the two in the waiters pocket total 30... in other words
Incorrect: 9x3+2=29
Correct: 25+3+2=30
(Simple Math: They payed 30, but should have payed 25. the 29 comes from the fact that the question misjudges you to think that they paid 9 each, but they have actually spent 30 each, with a 25 offer, plus 2 in the pocket and 3 between the men)
I didn't exactly understand the answer myself but that is exactly what it says in the book |

Shouldn't he keep 3z?
If he keeps 2z and gives the guys 1z each that makes 4z and he was given 5z. |

Yes it is. Tone it down. Also, shorten your sig, it's unnecessarily long (try taking out the line breaks).
As for your problem, the way you get 29 sounds right, but isn't. The math simply doesn't work the way it's described, which is why you don't come up with 30. |

I live in the USA, zenny is just game money... Ex: BoF, MMbn

Oh I keep thinking of USA money maybe that is why we see this differently... |

but it couldn't be divided evenly, there are no fractions of zenny |

i mind as well say it, they were charged 27
the bellhops money was included in the 27
the + 2 shouldn't have been done in the first place
Edit: well, that was quick, i need to come up with another math riddle, actually, that riddle came from Megaman bn 4, which got it from somewhere else |

I dunno what is wrong with your math but if you make me drag it out...
10 X 3= 30
30-5=25
25+3(their refund) + 2 (bellhops money)=30
I am not quite sure why your math is comming to 29, but maybe multiplin isn't the right thing? |

One was an error and the other one is too.
the first formula 10 x 3 is true
they did in fact pay the clerk 30, originally
but that was overchargeing so he sent 5 back
the bellhop kept 2 of 5
the guys payed 9 each in the end
but 3 guys times 9 equals 27
and, adding the two the bellhop took makes 29
the starting money was 30
by this math, it is 29
what is wrong with the math?
you cannot split into fractions

one problem, the total should be 30, but as your math has it's way, it is 29
Originally posted by Dracoon

9 each 3 guys
9 * 3 = 27
bellhop took two
27 + 2 = 29
needs to be 30
(putting it simply) this is what you need to solve, what is wrong with the above math?
