TWCP OTD (The Who Cares Puzzle Of The Day) - 7th of February, 2017
-
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.

Even you are right about the confusion between pages and sheets, but that's intentional... And in your case it led you to the wrong answer... ;)

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.

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?

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.

The worm could also have eaten through the bottom, went out, bought a suit, and after being elected to office hired someone to rearrange the books. Or anything else you care type. Read the problem; whilst it is true that anything that is not excluded from the answer may come into consideration, don't embellish the problem. Also, see Occam's razor[^].

Aah, yes, the Razor, one of my favourite philosophising tools, but occasionally shelved for playful pickiness. :)

Are we also not including other non-numbered pages like the preface, contents, 'This page intentionally left blank' etc?

It depends on the order of the books on the shelf and also on the language of the book. (Left to right reading order or Right to left reading order) Either way, there are only 2 possible answers for the four possible scenarios: 0 or the sum of the pages in both books.

Only wrong if we set aside Occam's Razor and consider that the worm did not burrow a straight hole through both parts in one go, as there is no such constraint set in the puzzle. :laugh:

Was it an African worm or a European one?
