While reading a newspaper you notice that four pages of one section are missing. One of the missing pages is page 5. The back page of this section is page 24. What are the other three missing pages?
Answer
Pages 6, 19, and 20 are also missing.
Newspapers are printed double sided, two pages to a sheet. The first and second pages are attached to the second-to-last and last pages—in this case, pages 23 and 24. The rest of the pages are attached as follows:
1-2 with 23-24
3-4 with 21-22
5-6 with 19-20
7-8 with 17-18
9-10 with 15-16
11-12 with 13-14
