TWCP OTD (The Who Cares Puzzle Of The Day) - 7th of February, 2017
-
BOOK WORM On the shelf there is a book of two parts. The first part has 972 pages (not including cover, but anything else), the second has 864 (same)... A curious worm ate itself thru the book starting with the front cover of the first part and until the very end of the back cover of the last part... How many pages it perforated on the way?
Skipper: We'll fix it. Alex: Fix it? How you gonna fix this? Skipper: Grit, spit and a whole lotta duct tape.
A real oldie - the two book parts you noted are adjacent to one another on books "properly" shelved. If you don't count the covers as pages, the answer is "none".

Zero - assuming the books are put on the shelf in order from left to right with the spines outwards. In that case the front cover of part 1 is adjacent to the back cover of part 2, so the worm ate through the front cover of part 1 and the back cover of part 2.

I wonder if this is a matter of age... :thumbsup:

And for my prize, I seem to recall that there's a Halavah stall in one of the markets (Machane Y'huda, perhaps?) - A kilo of their finest, assorted, will do for a start.

Yes - and do you mean I went through all of the _time and expens_e of answering the question for free? That's crazy.

If you try a remark like that again I'll tell O.G. on you. Don't think I won't. What a bunch of castings . . .

I don't get it, I definitely need a drawing here.

OK: Drawing in your mind's eye (illustration on bottom): Consider how a set of books is put on the shelf. Lowest volume number to the right and in sequential order. Next imagine your in the process of taking the first volume off the shelf. It's in your hand and the front cover is to your right. So it's not on the outside edge of the volume set. The back cover of book '1' the outside cover. In fact, for all books (not written in Hebrew or Arabic), when shelved, the left side is the back of the book and the right side is the front. Now - for the two volume set in the problem, the back of the second book, being on the left, is now touching the front of the first book.

t tThis would still be true, by the way, for books written right-to-left as their order on the shelf would be reversed, too.

BOOK WORM On the shelf there is a book of two parts. The first part has 972 pages (not including cover, but anything else), the second has 864 (same)... A curious worm ate itself thru the book starting with the front cover of the first part and until the very end of the back cover of the last part... How many pages it perforated on the way?
Skipper: We'll fix it. Alex: Fix it? How you gonna fix this? Skipper: Grit, spit and a whole lotta duct tape.
Was it an African worm or a European one?

It is quite reasonable to not count book covers as pages, although they may be leaves of paper. The first part has 972 pages, making 486 physical leaves of paper that are pages. The second part has 864 pages, or 432 leaves of paper that are pages. If we don't assume, as it is not stated in the puzzle, that the worm burrowed in straight line through both parts, it perforated 1836 numbered pages, or 918 leaves of paper.

Book covers are not book pages.

It did not, it just said a book has n pages, not counting the cover. If you mistakenly consider a cover to a page of a book, then the puzzle implies you should include covers.

Please justify this answer. What difference does it make that the books are adjacent to each other, if the worm still burrowed through all of both parts, except maybe the back cover of the last?

Very good, if the puzzle stipulated that the worm burrowed through both volumes in one straight line. In your drawing, the worm could very well have started between the two volumes, and burrowed to the left through the first one, then circled back to the right of the second one and burrowed left until the back cover of that one.
