tos4u: U will need to pick one box labeled as having 2 black marble. Pick d first mable and the second marble and see their color. U Wil then know the original label of dat box, then look for anoda box labeled as the color of the the 2 marbles u pick and exchange the label to the original u now found out then interchange then on the remainin two boxes without opening them,I think ua wrong. Lets be practical. Let capital letter represent d label and smal letter d content eg WW (wb), BB (ww), WB (bb). Using ur formula: if i pick frm WB (wch actually has bb), u suggestd i pick both. As i find its bb, u suggest i look 4d label BB (wch contains ww) and interchange it. Hello...? |

MoyoGENERAL: yeeeeeehhhhhh Please make sure that you know the correct answer to a puzzle before you post one. Your answer is wrong and I had already provided you with the correct answer. Here is your proof. Based on the solution that you provided. Box 1 contains WW, but is labeled BW (picked W and then conclude that it is WW since it is wrongly labeled) Box 2 contains BB, but is labeled WW (you simply interchanged the remaining two labels). Box 3 contains BW, but is labeled BB Now tell me, will your solution work if: Box 1 contains WW, but is labeled BB (picked W: no conclusion as to what this box contains. Could be either WW or BW. You can only conclude that it is not BB) Box 2 contains BB, but is labeled BW (Could be BB, WW, or BW since you have not concluded on the contents of Box 1 and Box 3) Box 3 contains BW, but is labeled WW (Could be BB, WW, or BW since you have not concluded on the contents of Box 1 and Box 2) Your solution is therefore wrong. I have provided you with the solution earlier (Second page). |

My guy am 100 percent right, see wen u pick out d 2 black marble look for d label on anoda box and put it on d d box which contain d 2 black marble, den instead of puttin d first label on d one u latter remove, jus interrchange on the one u never removed d label and put tht label on d secon label u latter removed, withot opening d other boxes, like i say u only need 2 marbles to determine them, thanks Am a mathematicians so i advice u check my xplainatn again ChukChinCol: |

Re: Believe Me, This Is Going To Make You Sweat!.the Best Of Puzzles. by MOBBDEEP: 4:49pm On Jul 15, 2014 |
You need to draw a problem solving table. Using this table, the following facts emerge since there are NO exact same way of giving and addition of all rows or columns must be 4: Deduced Fact #1~Alice was the only one who could give one each to all 4 sisters because she is the only one with 4 empty spaces to give. Others have only 3 or less spaces. Meanwhile, she can't take from Christy, Beth nor Edith again since she has already gotten her complete 4 from Beth. Deduced Fact #2 ~Edith was the only one who got 3 from Christy (from your statement) + 1 from Alice (from the deduced fact #1 above). Therefore, she can't get anything from Deborah,Beth (she has given all her 4 to Alice) nor herself. Hence, her 4 is complete. Deduced Fact #3 ~ Since Edith & Alice can no longer take from both Deborah again (their received 4 is complete), therefore, Deborah only has 2 people to give i.e Beth & Christy. Meanwhile, the sum must be 4 and it must not be 3 + 1 since your rule says no pattern of distribution/giving is the same. But Christy has already given 3 to Edith which meant she gave the remaining 1 to someone. What it means invariably is that Deborah can only give 2 each to both Christy & Beth. Deduced Fact #4 ~ Since all the 4 sisters had 1 each from Alice (from Deduced Fact #1), therefore both Christy & Beth now have 3 each (from the Deduced Fact # above). Which means both need extra 1 each from Edith to complete their 4. By way of deduction again, this implies that after giving Beth & Christy 1 each, Edith can only give her last 2 to Deborah, who so far has only gotten 1 from Alice. Deduced Fact #5 ~ Now that Deborah has 3, her last one will definitely come from Christy who is the only one who has not completed the 4. SUMMARY: Beth gave all 4 to Alice& received 1 from Alice, 2 from Deborah & 1 from Edith. Christy gave 3 to Edith & 1 to Deborah and got 1 from Alice, 2 from Deborah & 1 from Edith. Deborah gave 2 each to Beth & Christy and got 1 from Alice, 1from Christy & 2 from Edith. Edith gave 1 to Beth, 1 to Christy & 2 to Deborah while getting 3 from Christy & 1 from Alice. Alice gave 1 each to all 4 sisters & got 4 from Beth. Meanwhile, something tells me we should be able to apply Kramer's Rule of Matrices to solve this problem. Mathematician in the house!!!, help please. |

MissMeiya: [size=18pt]WE HAVE A NEW PUZZLE. No more answers for puzzle 1.[/size] MoyoGENERAL: This question requires no mathematics......referring to the person calling for kramers rule. It needs no chart as well. There are several possible solutions. First Deborah can't receive a book from herself and she can't receive from Beth as well because she gave all her books to Alice. Deborah must receive a book from Christy. And, Deborah will receive one book from Alice and two from Edith OR one book from Edith and two from Alice. Thus, Deborah received from Alice, Christy and Edith. |

saintneo:This puzzle has only one solution. How do you know this? Again, how do you know this? You based this on an unproved assumption. Logical proofs must give... proof. The OP even said answers must be explained. The answer is less important than the reasoning. Start with the given information, and use logic to PROVE the answer. |
Re: Believe Me, This Is Going To Make You Sweat!.the Best Of Puzzles. by saintneo(m): 6:38pm On Jul 15, 2014 |
MissMeiya: There are two solutions that I see for all conditions to be met. Christy must give a book to Deborah. This eliminates the duplication of 2-1-1 formation of giving by both Alice and Edith; consequently, either Alice or Edith can go for the 2-1-1 distribution formulae OR 1-1-1-1 distribution formulae. Only Deborah can use the 2-2 distribution formulae. 0-1-1-1-1 4-0-0-0-0 0-0-0-1-3 0-2-2-0-0 0-1-1-2-0 Alice and Edith can interchange distribution formulae. |
Re: Believe Me, This Is Going To Make You Sweat!.the Best Of Puzzles. by Nobody: 6:54pm On Jul 15, 2014 |
saintneo Here's the problem with this: you started with the correct answer and tried to work backward. I'll show you the problems in your proof: Christy must give a book to Deborah.This hasn't been proved yet.She could have given her fourth book to Beth. This eliminates the duplication of 2-1-1 formation of giving by both Alice and Edith;Christy could not give 2-1-1, because she gave 3 books to Edith. consequently, either Alice or Edith can go for the 2-1-1 distribution formulae OR 1-1-1-1 distribution formulae.This is not true. Edith CANNOT give 1 book to each sister. Why? Beth gave 4 books to Alice. Therefore, Alice cannot receive a book from Edith. 0-1-1-1-1This is a copy of the logic chart I made, except it is not labeled... My point is simply: logic puzzles always have a set of steps to solve them. Finding those steps will lead you to write a good proof. |

Re: Believe Me, This Is Going To Make You Sweat!.the Best Of Puzzles. by MoyoGENERAL: 6:42am On Jul 16, 2014 |
good morning guys,,having waited more than 36 hours after posting puzzle 2, I feel its time to give up the answer and explanation...so we won't wait till eternity for the first 8 person.... Alice.....Beth.....Christy......Deborah.....Edith Alice. 0...........1............1...............1................1 Beth. 4............0...........0..............0.................0 Christy. 0............0............0..............1................3 Deborah. 0............2...........2...............0................0 Edith. 0............1...........1...............2................0 This can be solved perfectly with a grid... We are going to fill the grids with the number of books given to and received by each sister i assumed that names at the left means "gives" and names at the top means receive" ....eg. ColumnBA reads beth gives 4 books to alice.etc We can see that Alice already has 4 from beth, so no other sister gave her any, so we can put zero in the rest of the column and rows of beth We notice that one sister gave one book to each of her sisters, that sisters had to be Alice, because no other sister can give alice extra books cos she has 4 already...so we fill the remaining rows for Alice with 1... Next check the column of edith, edith has now received 1 extra from alice with the 3 from christy to make 4... Therefore we fill the rest column with zero..... Next, you will observe that deborah must receive 3 more books to make 4 so that we will fill up the column,,,at this point, deborah has only 3 people possible to give her 3books altogether( christy, deborah and edith)..but deborah cannot receive book from herself, so the only possible option is to receive books from christy and edith, however, christy has only 1 book left to give, therefore she gives 1 to deborah and Edith must give 2 to deborah to complete her 4. ...After filling the remaining columns of deborah, you can now fill the remaining rows of christy cos she has given out her 4 books.... Seeing the table at this point, you will be able to deduce that deborah was the sister that gave 2 books each to two of her sisters, so we fill the remaining two rows of Deborah with 2 At this junction, we are left with the remaning rows of edith, which obviously will be filled with 1 each to make 4 NB.. Please ensure you prepare an empty grid and follow the steps above... So the final answer is... Deborah will receive: 1 book from Alice, 1 book from Christy, and 2 books from Edith.. ..... Note deborah cannot receive 2 books from Alice and 1 from Edith, cos if that happens then edith will be giving a book to herself which is absolutely impossible... |
