First, from the choices of answers, I would assume that duplicates count. That is page 1 and page 11 would mean 3 digits. Is that included in the statement of the problem? As a hint, how many single digit numbers? So, using those how many zeros would you use for the 100's, 200's, and 300's, for those first numbers? How many ones for the 100's? and so forth.
