And to show a picture of the solution:   First page of each book are on the right of each book. Last page of each book are on the left of each book.  1   2    3 --- --- --- |  ||  ||  | |  ||  ||  | |  ||  ||  | --- --- ---    A     B   However, in reality, in order to get to PAGE ONE of VOLUME ONE located at "A" the worm would have to start at the far left OR eat non-horizontally OR the book was open to begin with OR the worm somehow got to that position. BUT since the question uses the word "from", then it is correct.   IP Logged A job is not worth doing unless it's worth doing well. rmsgrey Uberpuzzler     Gender: Posts: 2873 Re: Book worm   « Reply #3 on: Nov 29th, 2003, 6:03am » Quote Modify My books are upside down and in conventional order...   (thanks to my friend for pointing this out) IP Logged kumaran Guest Re: Book worm   « Reply #4 on: Jan 29th, 2004, 4:08am » Quote Modify Remove worm has eaten 1 inch of book IP Logged Pages: 1  Reply Notify of replies Send Topic Print Forum Jump: ----------------------------- riddles -----------------------------=> easy   - medium   - hard   - what am i   - what happened   - microsoft   - cs   - putnam exam (pure math)   - suggestions, help, and FAQ   - general problem-solving / chatting / whatever ----------------------------- general -----------------------------  - guestbook   - truth   - complex analysis   - wanted   - psychology   - chinese « Previous topic | Next topic »
