A book was printed using a total of 255 digits for the page number (pg.42 = 2 digits ) How many numbered pages are in the book?
-
the first nine pages used 9 digits
the next 90 pages used 2 digits each for a total of 180 digits - we're up to 189
The number of pages using 3 digits will go far past your 255 page max so lets figure this out. 255-189 = 66 digits left. each subsequest page needs 3. so 66/3 = 22.
9+180+22 = 211 pages
the next 90 pages used 2 digits each for a total of 180 digits - we're up to 189
