pages 56 and 57
If one of the pages is numbered p, the other is p+1. So p*(p+1) = 420 That is, p2 + p - 420 = 0 which factorises as (p - 20)*(p + 21) = 0 That implies that p = 20 or p = -21. Assuming that pages do not have negative numbers, p = 20 and then the other page is p+1 = 21.
pages 42 and 43 [you take 85 down one, then halve it, and as it's a book obviously one page will have a higher number that the other.]
52 and 53
381 digits.
They are 44 and 45.
40 & 41
The book is opened to pages 26, on the left, and 27, on the right. The product of 26 times 27 is 702.

The page numbers would be 166 and 167.

The odd numbered pages are typically on the right side of the book when you open it; the even numbered pages will be on the left.
pages 56 and 57
Let the two facing pages be represented by x and (x+1). Since the product of the page numbers is 1056, we have the equation x(x+1) = 1056. This simplifies to x^2 + x - 1056 = 0. By solving this quadratic equation, we find the page numbers to be 32 and 33.
