Newspaper Caper Puzzle - Solution

The Puzzle:

Newspaper Caper
Here's a newspaper made of 8 large sheets of paper folded in half. The newspaper has 32 pages altogether.



The first sheet contains pages 1, 2, 31 and 32.

I pick up a sheet containing page 25. What are the other pages that this sheet contains?

Our Solution:

First of all you had to work out that page 26 was on the back of page 25. Then you had to notice that the numbers were arranged in pairs, with the first pair adding up to 32 and the second pair adding up to 34.

Then it's easy:

32 − 25 = 7

34 − 26 = 8

So the four pages on this sheet are 7, 8, 25 and 26.
