When setting the type for a book, a publisher wanted to use a particular font to number the book's pages. They found that they needed 2775 digit characters for the whole book.
How many pages does the book contain?
961 pages
Pages 1 - 9 contain 9 numbers --> 9 characters
Pages 10 - 99 contain 90 numbers --> 180 characters
Pages 100 - 999 contain 900 numbers --> 2700 characters
Add them up to get an idea where you stand. 2700 + 180 + 9 = 2889 characters; TOO HIGH.
From here, I just did the 'ol "cut in half and try again" method until I got 961.
