Goofy Math Riddle
This one tends to stump normal, ostensibly intelligent people. I suspect, however, that the denizens of this swamp will nail it quickly.
3 guys check into a motel. The desk clerk says the room is $30, so each guy hands him a $10. The 3 guys go to the room. A bit later, the manager sees the registration and tells the desk clerk he made a mistake and the room is only $25. desk clerk takes 5 $1 bills and heads to the room. The 3 guys in the room thank him, each takes $1 back and gives the desk clerk a $2 tip. Now each guy spent $10 - $1 change = $9 x 3 = $27 + $2 tip = $29 Where's the other $1 go? (note): please take any speculation on what the 3 guys are doing in one room over to the *homosexuality* thread [img]/images/graemlins/smile.gif[/img] |

Re: Goofy Math Riddle
I remember this riddle from when I was a kid [img]/images/graemlins/smile.gif[/img]
It's all in the problem statement actually. The deceiving part is that 9x3=27, and 27+2=29. Of course, this is true, but it's far from an accurate picture of how the $5 is disbursed. It's really 9x3=27, and 27-2=25. So the entire $5 that the manager gives back is accounted for. |

Re: Goofy Math Riddle
Well actually each dude has $1.
The Hotel has $25. The Clerk has $2. ($1 x 3) + $25 + $2 = $30 That's an old riddle, haven't seen that one for a while. |

Re: Goofy Math Riddle
Together they spend $25 on the room. So each guy spends 25/3 = 8.33$ on the room. They got $1 change each and together left a tip of 2$.
Adding all the money you get (3 x $8.33) + (3 x $1) + 2$ = $30 In the question, they only account for the boys' 9$ a piece on the room, but that's incomplete, they actually spent $8.33 each on the room and each got $1 back. So the equation in the question should have been (3 x (8.33 + 1)) + $2 tip = $30. So the answer to the question is that the other $1 goes to the guys having homosexual sex in the room [img]/images/graemlins/grin.gif[/img]. edit:grammar |

Re: Goofy Math Riddle
Each guy spent $8.33 on the room and $.67 on the tip. The exchange caused fractions in the payments to appear which, when paid in sum, looked like whole dollars, hence the confusion.
