Question

How many pages are in a book, if the total numbering on all the pages (from the first to the last) required 720 digits?

Answer 1

276

Explanation:

We can model this with the equation: a(1) + b(2) + c(3) = 720, where a is the amount of 1-digit numbers, b is the amount of 2-digit numbers, and c is the amount 3 digit numbers that can fit with 720 digits of page numbering. We get a = 9, b = 90, and c = 177. So, we now add the 3 numbers.9 + 90 + 177=276, so there are 276 pages in the book.

Hope this helps!
