I caught the "typo" on the A, that wasn't the issue. Even with the "A" your numbers were incorrect.  It was very close, and I hope you have an opportunity to try to solve other challenges. We have 50 more after the current one. |

Oh! Sorry, I didn't realize you meant that as a guess for the puzzle, my fault. 
I don't have the book with me, so I don't remember if that's the correct answer or not. I will check it and post back later this evening. |

This is the correct answer for the challenge. I would have preferred to see your work  but the answer is correct, as posted.
Prizes will be awarded shortly. |

e$1000 has been donated to Kiman4 for winning e$ Challenge #50. As a first time winner with a net worth under e$50K Kiman4 has also been awareded not one but two Barren Desert properties. You can keep them / sell them / do whatever you like.
Aren't you glad you posted the wrong answer for #49 now? You would not have received the first-time winner bonus otherwise.
Here's the solution as posted in the book:
Benjamin walked L miles on foot. Since the three travellers arrived at the same time, Benjamin and frusnak must have walked the same distance; since Benjamin and frusnak walk at the same speed, they walked an equal amount of time.
frusnak walked L/6 hours. (Dave note: the 6 comes from the speed of 6 miles per hour that frusnak walks.) During this time, Im Not Warren Buffett drive (8 - 2L) miles back to meet Benjamin (the length of the road, minus L walked by Benjamin and L walked by frusnak), and (8 - L) miles with Benjamin to town; in all, (16 - 3L) miles, which took him:
| Code: | 16 - 3L
-------- hours
30 |
Since Im Not Warren Buffet took the same time to reach town after dropping frusnak that frusnak took:
| Code: | L 16 - 3L
- = -------
6 30 |
And L = 2 miles
The total time of the trip was:
| Code: | L 8 - L
- + ----
6 30 |
which is the time Benjamin walked plus the time it took Im Not Warren Buffett to drive him (8 - L) miles to town. Substitute 2 for L and the time is 32 minutes. |

I actually realized I had an error, which was that they drove for 8 minutes back, but then I knew that your answer was the correct one, so it didn't think it would do me any good to repost it. |

e$ Challenge #51
Compete for e$1000! (The prize amount was increased starting with e$ Challenge #15.) 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 51st e$ Challenge Puzzle! Complete this magic square with the integers from 7 through 36. Each horizontal, vertical, and diagonal must add up to 111. For formatting purposes I have placed a dot "." where each missing number should be. Replace the dots with the numbers to solve the puzzle. There have been other puzzles like this (less complex) earlier in this topic if you want to browse back and see some sample solutions

I don't know how you figure these things out. I can get some of the math or logic problems, but I look at these and shrug and say to myself, "Why bother?"
I've verified the number, and your last answer looks good. I will be curious to check your answer against the book when I get home tonight. In any case, if you wanted the e$ to invest today I'll go ahead and pay your prize now, and I'll post the next problem tonight. |
