Answer: 29, 30, 35, 36
Step-by-step explanation:
As per your info about first page.
The paper containing 64 has following other pages
On the back of 29, it is 30. The pages are such that for each page p, 65-p will be also on the same page.
Then,
65-29= 36
65-30 = 35
So the four pages in this sheet are 29, 30, 35, 36.
