The page numbers in a book use 810 Digits. If the book starts with page #1 how many pages are in the book.
I think it's a trick question, because digits is underlined. Is the answer 810? What does it mean by uses 810 Digits?

yes you are correct

It there were 99 pages, the number of digits used would be 9 (with one digit) + 2x90 (with two digits) = 189. Each additional page will require 3 digits, and you need 621 more digits. That requires 207 more numbers. That would make the number of pages 306. Check my thinking.
