Newspaper folded in half
If we pick up a sheet containing page number 45. What are the other
pages that this sheet contains?​

Answer 1

Answer:

19,20,45,46

Explanation:

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

Then,

65-45 = 20

65-46 = 19

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

Answer 2

The answer is 19, 20, 45, 46.

Explanation:

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

Hence, 65-45 = 20

65-46 = 19

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