Best ResponseYou've already chosen the best response.2From Page Number 1 to 9 we use 1 digit per page => digit used = 9 From page Number 10 to 99 we use 2 digit per page => digit used = 90 *2 = 180 From page Number 100 to 252 we use 3 digit per page => digit used = 153 *3 = 459 Therefore total digit used = 9+180+459 = 648

Best ResponseYou've already chosen the best response.0Sorry, the digits 0 to 9 have been used to number the pages.. Your question said nothing about having to count them more than once.
