Answer 2

To determine the number of digits printed for page numbering in a book, we need to consider the starting page number and the total number of pages in the book.

In this case, the book starts numbering from the 3rd page and has a total of 65 pages.

To calculate the number of digits printed for page numbering, we can follow these steps:

1. Calculate the number of pages from 1 to 9: Since the book starts numbering from the 3rd page, the first two pages (1 and 2) are not numbered. Therefore, we have 7 single-digit page numbers (3, 4, 5, 6, 7, 8, and 9).

2. Calculate the number of pages from 10 to 99: Each two-digit page number requires two digits. To calculate the number of two-digit page numbers, we subtract the number of single-digit page numbers from the total number of pages. In this case, we have 65 - 7 = 58 two-digit page numbers.

3. Calculate the total number of digits: Multiply the number of single-digit page numbers by 1 (since each single-digit page number requires one digit) and multiply the number of two-digit page numbers by 2 (since each two-digit page number requires two digits). Then, add the results together. In this case, we have (7 * 1) + (58 * 2) = 7 + 116 = 123 digits.

However, it's important to note that the calculated result is 123 digits, which is different from the expected result of 119 digits that you mentioned. Therefore, please double-check the starting page number and the total number of pages in the book to ensure the accuracy of the information provided.
