Calculating the Number of Pages in the Book

To calculate the number of pages in the book, we can use the information provided. The first page number is 143, and the last page number consists of the same digits but in a different order.

Let's denote the first page number as "abc" and the last page number as "cba", where a, b, and c are digits. The difference between the two page numbers is the same as the difference between the two numbers "abc" and "cba".

The difference between "abc" and "cba" can be calculated as: abc - cba = 143 - 341 = -198

The negative result indicates that the book has 198 pages.

Therefore, the book consists of 198 pages.
