Answer 2

The question is in Kazakh language and it means: "Answer in detail. The book is numbered with 3 digits starting from the third page. All pages of the book are numbered with 1315 digits. How many pages are numbered in the book?"

To answer this question, we need to find out how many pages are numbered with 1, 2 and 3 digits respectively. Then, we can add them up to get the total number of pages.

Let's start with the pages numbered with 1 digit. There is only one such page, which is the first page. However, the book is numbered starting from the third page, so we can ignore this page.

Next, let's consider the pages numbered with 2 digits. There are 99 such pages, from 10 to 99. However, the book is numbered starting from the third page, so we need to subtract the first two pages from this count. Therefore, there are 99 - 2 = 97 pages numbered with 2 digits.

Finally, let's look at the pages numbered with 3 digits. There are 900 such pages, from 100 to 999. However, the book is numbered starting from the third page, so we need to subtract the first two pages from this count as well. Therefore, there are 900 - 2 = 898 pages numbered with 3 digits.

Now, we can add up the pages numbered with 2 and 3 digits to get the total number of pages. We have:

97 + 898 = 995

Therefore, the book has 995 pages that are numbered with 3 digits starting from the third page. All pages of the book are numbered with 1315 digits, which means that there are 1315 - 995 = 320 pages that are not numbered. These pages could be the cover, the table of contents, the introduction, the appendix, etc.
