In numbering the pages of a book, a total of 510 digits were printed. If the first page is numbered 1, how many pages does the book have?
(A)170 (B) 199 (C) 200 (D) 206 (E) 198
-------------------
1 to 9 = 9 digits
10 to 99 = 180 digits
----------------------
189 used, 321 left of 3 each
321/3 = 107 pages starting at 100
---> 206 pages total
Why couldn't you figure that out?
