You've got too many operations.  You should be able to do it in six "pours" only... |

| The operations may be correct, but there were too many of them. You should be able to come up with a series of "pours" that ends up with the required percentages in just six steps. |

Yeah but are the pours from the main casks considered pours? I remember a similar problem but it was with paint and buckets. Same idea, but if you dont count the out pours from the 100L casks, you shoud get six. |

Every operation - including those from the 100L casks - is counted.
Here is a hint: the inclusion of the 25L cask is a red herring; you do not need it to solve the challenge in six pour operations. |

Benjamin owns three casks of 100 liters, one of 50, and one of 25. The 100 liter casks are filled with Burgundy, Bordeaux, and Algerian wine respectively. The small casks are empty.
To make three qualities of wine, Benjamin mixes the three wines, using the five casks exclusively.
After six operations the three large casks are again full. The first is 1/4 Burgundy, 1/2 Bordeaux, and 1/4 Algerian. The second is 1/4 Bordeaux, 1/4 Algerian, and 1/2 Burgundy. The last is 1/2 Algerian, 1/4 Burgundy, and 1/4 Bordeaux.
1. Pour 50L of Burgandy from 100L cask to 50L cask.
2. Pour 50L of Bordeaux from 100L cask to 50L cask of Burgandy. Creating a 50/50 mix.
3. Pour 50L of Algerian from 100L cask to 50L cask of Bordeaux. Creating a 50/50 mix.
4. Pour 50L of Burgandy/Bordeaux mix to 100L cask Algerian. Completing the third mix.
5. Pour 50L Bordeaux/Algerian to the Burgandy/Bordeaux cask. Completing the second mix.
6. Pour the Burgandy in the 50L cask to the Bordueax/Algerian mix, creating the first mix.
Since you gave a hint, Dave, I'll take half of the prize. |

Nope, Grim gave me his money to give away, and that's what I aim to do. I'll pay out the full amount.
Thanks for reminding me about payouts... I never paid off the image for the What Am I? contest either, because I was waiting to post the other pictures first.
I will take care of both of these tonight.  |

e$ Challenge #54
Compete for e$5000! (The prize amount was increased starting with e$ Challenge #15, and then again to e$5,000 with #52.) Solve the puzzle and win! ... first winning answer to each puzzle. Some of the puzzles are going to be actual math problems, others require logical thinking instead. Each puzzle comes from a book I bought a while back. The rules:
- The answer in the book is final. Blame the publisher, not me, if you don't agree
- The first person to post the correct answer wins. Posting only, no PM's please.
- Edited posts are disqualified, even if you have the correct answer. The most recent (last) post by you for that puzzle is the only one that will be used, so if you need to make corrections simply enter another post for the challenge.
- You cannot win two challenges in a row, so the previous winner is not eligible for the next challenge.
- You may win more than one challenge, just not two in a row.
I will try to post one puzzle every other day. The puzzle will be posted first, then the following day (if available) a winner will be announced. Then the arguments or discussion about the solution can commence.  If no correct solution has been provided then the puzzle will be extended until a winning solution is provided. The puzzles get more challenging as we get further into the book.
Grand Prize
The book has 100 puzzles. Each individual winner gets one lottery ticket per win. Once all 100 puzzles have been posted (and solved) I will draw three winning tickets from a hat. Each winner will get to pick one of 3 mystery portfolios. The portfolio will have an initial value of e$2000 as of the end of February, 2006. Each has been invested as completely as possible into one stock from the S&P 500 chosen at random. The winners will have no idea which portfolio is worth the most. The first person drawn will get their pick of all 3 portfolios, the second drawn picks from between the two remaining, and the third drawn gets stuck (or lucky) with the last one available. The holding will be sold at current market price as of the end of the contest and the e$ transferred into your account. Your name may be drawn more than once, so the more e$ challenges you win, the better your chances of winning one of the three portfolios.
The stocks were randomly selected and purchased at market open March 1, 2006. e$2000 worth of shares of each of them were put into a secret account. These will become the grand prize portfolios, and the final value will be determined at market close on the day the last puzzle is solved and the e$ prize awarded.
Thanks for playing
Ready?
Here's your 53rd e$ Challenge Puzzle! How many ways can you read OSLO off of the following diagram, using letters that touch each other? Any "O" can be both the first and the last letter in the same OSLO.

When Grim dumped his fortune on me a while back he suggested I could increase the prize money for the challenge topics I've been running. So there you go.
