They are both equal. You get the teespoons of water and wine from somewhere else. (edited by blackfire on 04-18-04 11:12 PM) |

Don't have to get them from somewhere else. If you just have the two glasses, and put a teaspoon of glass A in glass B and then put a teaspoon from glass B into glass A, they'll have equal contaminations. Unless I made a mistake working it out | |||

Yes but Jagori if you you put a teespone of glass A in glass B mix it around it then becomes a glass B/A solution. So then if you put this new B/A solution into glass A it becomes A/B/A. But then again my brain could be working over time and i have this whole thing confused. So maybe you are correct. |

The thing is, when you add some of A to B, you decrease the total amount of substance in glass A and increase the total amount in B. And unless I'm mistaken, the ratios work out. | |||

But the question is which glass has more of the other substance in it. So unless you got the teespoons of substance from somewere else then wouldn't the wine glass have more water in it because of what i said before. "You put a teespone of glass A in glass B mix it around it then becomes a glass B/A solution. So then if you put this new B/A solution into glass A it becomes A/B/A." |

I dont think it would quite work out, It would be hard to get the exact ratios, It would be very close but not exact I don't think |

Well theres got to be an answer or their would be no point for the question and i think what blackfire and Jagori said would be around right and more close to the answer | |||

Say the first glass has 10 teaspoons of A in it, and the other one has 10 teaspoons of B in it (this will work with any amount of teaspoons, but I'm just plugging in 10 for example's sake). You take one teaspoon from A and put it in B. Now the first glass has 9 teaspoons of A, and the second has 10 of B and one of A, for a total of 11 teaspoons. Now if you take a teaspoon from the second glass, that teaspoon will be 10/11 B and 1/11 A. Put that back into the first glass and you have 9 1/11 A and 10/11 B, for a total of 10 teaspoons of stuff. Subtracting what you took from the second glass leaves you with (10 - 10/11) B and (1 - 1/11) A, or 9 1/11 B and 10/11 A. So now glass 1 has 9 1/11 A and 10/11 B, and glass 2 has 9 1/11 B and 10/11 A. Equal contamination. If you want to use any amount other than 10, it should work (I just tried it with 15 and 20).. or even if you want to make a general formula, plug in 'x' and it should still work out. Feel free to point out mathematical errors (edited by Jagori on 04-19-04 05:32 PM) |

Im going to give Jagori the points because he had the correct answer in the first post..... _____Score_____ NSNick - 9 Jagori - 8 Felix - 4 Edsgravy0 - 1 _______________ Puzzle 9 ( 4 points) The frustrated policemen. The police in Venezuela have been trying to arrest a notorious criminal for some time. They know where he lives, and on several occasions, they have obtained a warrant for his arrest and went to his house. However as soon as they get there, he locks himself away in his bedroom. The police then go away frustrated.... why? |

Is it because the police are only good at solving crims and aresting people that they don't know how to enter or open a door? | |||

Actually in the last question about the water and wine i had the asnswer correct first. (edited by blackfire on 04-20-04 04:35 AM) (edited by blackfire on 04-24-04 07:02 AM) |

KATW gave me the points for the water/wine one because I got it right first try and backed up my answer, instead of just guessing all possible combinations. But I really don't care about the points, so if they're so important to you, and KATW wants to give them to you then I'm fine with that. I'm just here for the puzzles Originally posted by tinzeeeNo, the police are regular, competent police officers. (edited by Jagori on 04-20-04 02:38 PM) |

Originally posted by blackfireI only take THE one and only answer. You said teh you needed to get the wine and water from somewhere else, but thats not true... In a deeper explanation, when you make the two transfers back from each glass, the volume stays teh same in each. So any water not in the water glass will be in the wine glass, and any wine not in the wine glass will be in the water glass. There is no other place it can be As for the police one, there is nothing special about his bedroom, its only a simple lock, but thats not what is keeping them out.... think a bit "outside the house" if you will. |

Originally posted by Kirby all the way Ok the way in which you worded this suggests that you want to know which is more contaminated not which has the greater volume. In this way my first answer was correct because: If you put a teespone of glass A in glass B mix it around it then becomes a glass B/A solution. So then if you put this new B/A solution into glass A it becomes A/B/A. A = Water B = Wine If you wanted the answer to be equal the you must have gotten the teaspoons of substance from elswere. |

Wrong again im afraid.... We have here glass A, and Glass B. One of them contains water, and one of them contains wine. We take one teaspoon from glass A, and put it in glass B. Then we have Glass A being pure, and glass B being contaminated, but since they are not equal, we take a teaspoon from glass B and put it in glass A. Now the glasses are equal in volume, and they are both contaminated. Now, in glass A, we have water mixed with wine, and in glass B, we have wine mixed with water. The total amount of water or wine never changed, and the volumes remained the same. The water and wine are split up in 2 different glasses now, Glass A, and Glass B. The amount of water in glass A + the amount of water in glass B will equal the original amount of water, like wise with the wine. So you see, any water that is not in the water glass is in the wine glass, and the wine that was there must be in the water glass, because there is nowhere else for it to go. So the water glass must contain the same amount of wine that the wine glass contains water. Therefore, the two glasses are equally contaminated. Just try and question that logic |
