A bookworm eats from the first page of an encyclopedia to the last page in a straight line. The encyclopedia consists of ten 1000-page volumes and is sitting on a bookshelf in the usual order. Not counting covers, title pages, etc., how many pages does the bookworm eat through?
On a book shelf the first page of the first volume is on the “inside”, so the bookworm eats only through the cover of the first volume, then 8 times 1000 pages of Volumes 2 – 9, then through the cover to the 1st page of Vol 10 for a total of 8,000 pages.
Note: The question asks how many pages, not how many sheets of paper.
Smoke. It rises then slowly dissipates in the air. Smoke signals send messages and incense is used in religious ceremonies. Anyone who’s sat at a bonfire knows smoke in your eyes can make you cry when the wind changes direction. Smoked meats are a tasty treat, but if you see heavy smoke (i.e. from a fire) then run. Or stop drop and roll if the fire already caught you.
Two men are standing on one side of a bridge and two women are approaching them. One of the men says, “Here comes my wife and daughter” to which the second man replies, “Here comes my wife and daughter”. If they have not married the same woman and the women aren’t pregnant, how is this true?
Wind (or anything blown by the wind). It moves all over, reaches the rich and the poor equally and no one knows exactly which way the next gust of wind will blow. You can’t see the wind, but you can see what it blows, like leaves or dust.
