Question 482160: Hui Juan was asked to number the pages of a book. After numbering all the pages, she found out that she had used a total of 1296 digits. How many pages were there in a book? Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! There are 9 single digits, 90*2 double digits and 3x triple digits.
9+180+3x=1296
3x=1296-189
3x=1107
x=369
369+90+9=468 pages
