So as a mechanic i curse at engieers all the time, they always say the math is right, it will work. so i hit them with this,
Three hunters are in the woods and find it to be a crapy day. So they deside to go in to town and get a hotel room for the night.
The room costs $30, each hunter puts in ten dallors,
Durning the night the mananger is doing the books an realizes he over charged them for the room, it should have only cost
$25. He gives the bell boy the change, $5 and tells him to give this to the men in room xxx
While in the elivator the bell boy says to himself, nuts to this im taking $2 for myself, and puts it in his pocket.
He gets to the room and gives the men there change,
Now if each man gave $10 and got $1 back, they only put in $9 for the room right?
3x9 is 27 and the $2 the bell boy took = 29, where did the other dallor go? |

The $27 the men have paid covers the $8.33 each out of the $25 and the $0.66 each for the $2 tip. The $3 is what they keep.

| let me show u why they say engineers are right, i am almost one my self, see at the end when u say 3x 9= 27, u cant add 2 on top of that bcz then each of them would have paid more than 9, they each paid 9 totaling to 27 which was 25 for the room and 2 for the tip:D . so for the room they each paid 25/3=8.3333, then with the remaining money from the 9 bucks which is 9-8.333=0.66 each , times 3 of that wich is 2 bucks was the tip , soo in other words wut chrome dragon said:D |

thats just one of those slip up questions, if you dont pay attention, you slip up.
BlueCarGirl was the first to post this i believe.
I much prefer questions like:
In order for an object to change movement to the opposite direction, it has to completely stop moving, even if for a fraction of a second.
So if a Train is going 200 KPH in one direction, and a fly is going in the opposite direction, and the 2 collide...does the train stop for a split second at the same time as the fly? If not how is it possible for the fly to stop while the train is still moving?
I love physics. I spent all of Grade 12 trying to prove mathematically that einsteins theory that light cannot exceed the registered speed of light (3.00x10^8 m/s) is wrong....and then a couple of months ago, they managed to speed up light beyond that...yay They also managed to slow light down so that it wasnt moving...
Light is a particle and a wave....its a wavicle!
I feel like such a geeky nerd right now... |

I used to lovvvvvvvvvve physics problems.......... The old light is a particle and a wave phenomena.........
WHat is interesting is that math does not normally deviate from its principles............where as the problem that Chris posted shows that math is potentially never wrong.........but the english language can definitely be wrong. |

Your not back at an equal $30 in the end |

$25 for the room + $2 for the tip = $27 paid. They each get $1 in return, ie $3. $27 + $3 = $30. Not that complicated. |

ya i am an engineer they only teach me math and shit like that, no english courses at all:D . these r simple problems, were its not that hard to find the hole in it, try these , its not a problem but its fucked up
0=0 right?
17-17=0 right? and 35-35=0 right?
so 17-17=35-35 this can also be ritten as
17(1-1) = 35(1-1)
now divide both sides by ( 1-1)
u get that 17=35

just to let you know...your comment about engineers, i sense a little jealousy that they're a tad bit smarter than you.
so here's the answer to your stupid riddle:
this question is about perspective.
the guys paid 10 each for a total of 30.
the owner only wanted 25 so sent back 5 from the 30.
the bell boy kept 2, meaning the three people totalled 27.
SUBTRACT 2 from the 27 to arrive at the expected price of 25...you don't fucking add it...remember, there was a net change of 5.
so in short, what happens here is that instead of adding 2 to the 27, you should be subtracting...nothing happened to the dollar...the question is just worded funny.
satisfied?
p.s. i'm an engineer. :thefinger |

Your theory is simple. You are not allowed to divide both sides by an interacting equasion (you must work it through), you can do it with common terms. Therefore, it is not correct to divide both sides by (1-1). Think about it. You added the (1-1) behind the 17 and 35 in order for them to equal zero, then you just took away the (1-1). You can't do that.
If you work it all out 17(1-1)/(1-1) = 35(1-1)/(1-1)
you get (17-17)/(1-1) = (35-35)/(1-1) therfore both sides are equal to 0/0 or 0 |

you do whats in brackets before you divide BEDMAS. so you are left with division by 0.

CS PIPE has NPS 2 TOE BW to CS PIPE with NPS 2
Translation: Carbon Steel pipe has national pipe size of 2 inches in diamter threaded on one end. Butt-welded to carbon steel pipe with national pipe size of 2" diameter. |

generally, i prefer to respond to inquiries written in proper english...
but your theory is dividing each side by 0...you can't do that.
ya you're going to tell me you're not, you're dividing be (1-1)...don't be stupid, that's mathematically 0. |

| ok that is wuts wrong with the theory i am dividing by zero,but i asked u nicley so dont be a fucken dick about it. |

Ok, so I went with Tube instead of pipe.
