Answer 2

This is a mathematical problem that requires some logical thinking and algebra skills. The question is asking how many pages are missing from a book that has some pages torn out. The first page of the torn out section is numbered 213, and the last page is the same number but with the digits reversed, i.e. 312.

To solve this problem, we need to find out how many pages are in the torn out section, and then subtract that from the total number of pages in the book. We can use the following steps:

- Let x be the number of pages in the torn out section. Since the first page is 213 and the last page is 312, we can write an equation: 213 + x - 1 = 312. This means that if we add x - 1 pages to the first page, we get the last page. - Simplify the equation by subtracting 213 from both sides: x - 1 = 99. - Add 1 to both sides to solve for x: x = 100. This means that there are 100 pages in the torn out section. - To find the total number of pages in the book, we need to add the pages before and after the torn out section. We know that the page before the torn out section is 212, and the page after the torn out section is 313. So, the total number of pages in the book is 212 + 100 + (313 - 312) = 313. - To find the number of pages that are missing from the book, we need to subtract the number of pages in the torn out section from the total number of pages in the book: 313 - 100 = 213. This means that there are 213 pages missing from the book.

Therefore, the answer is 213. I hope this explanation helps you understand the solution.
