Hello to all of you guys here... I'd like to post a number puzzle, which had been brought to many forums, but yet nobody can work it out properly. I'm not a puzzle mania, this just really disturbs my mind. I hope you guys here can help me. This number puzzle is in .xls file format. It looks like HITORI, but it's not. Since here I can't attach .xls file, I put it (name: sept09A.xls) at: http://www.artofproblemsolving.com/Forum/viewtopic.php?t=171338&sid=dbfa1e1099d59aa7b0714fb0b192b6e4 There are tables contain of 10 rows (1,2,3,...,10) each. Each table contains of numbers, which here I give example 1 to 40, that should be found its relationships/patterns, so all of the numbers have to be fit in a certain rows in all of the tables. In EACH table there will be no same numbers vertically, horizontally and diagonally Tables 1-20 in sheet #2, Tables 21-32 in sheet #3, Tables 33-44 in sheet #4,..., Tables 273-284 in sheet #24. I name and arrange the tables just like that, though you can do else. In sheet #1 you can see Tables 1-20 have filled with numbers 1 to 350. In sheet #25 you can see that total amount of the numbers in each rows are almost its average, so this isn't random and it should have a solution, shouldn't it? (I hope this can explain the problems clearly). Thank you to those who want to pay attentions and interested in this puzzle.
P.S: 1. Because of their similar shapes, in sheet #26 & #27 I rearranged the tables that I think could be the "keys" of this puzzle, and I put the file (name: #26.xls) in my latest post there. 2. This "big sizes" puzzle is really tough, perhaps geniuses can only crack it...??!!
