Puzzle | Newspaper folded in half

A newspaper is made of 16 large sheets of paper folded in half, giving a total of 64 pages.

• The first sheet contains pages 1, 2, 63, and 64.
• Each sheet always has 4 pages (2 on the front, 2 on the back).

If we pick up the sheet that contains page number 45, what are the other three pages on the same sheet?

Check if you were right - full answer with solution below.

Solution :

On the back of 45, it is 46.
The pages are such that for each page p, 65-p will also be on the same page.

Then,
65-45 = 20.
65-46 = 19.

So, the four pages in this sheet are 19, 20, 45, 46.
