Well, well, well, looks like we've got a little math mystery on our hands. Let's see, if the product of two numbers is 600, those sneaky little page numbers must be 24 and 25. Why? Because 24 times 25 equals 600. Case closed, Sherlock!
The book is opened to pages 26, on the left, and 27, on the right. The product of 26 times 27 is 702.
They are pages 42 and 43 because the product of both numbers is 1806
42 and 43 because 42*43 = 1806
Let the page on the left be ' X '. Then the right-hand page is " X + 1'.Thus x ( x + 1 ) = 2550 = [ X squared ] plus XTry making X = 50.50 x 50 = 2500Then ( 50 x 50 ) + 50 would equal 2550Since this is true, then the pages must be numbered 50 & 51
First 9 pages = 9 digit. That leaves 142 digits. @ 2 digit per page, that is 142/2 = 71 pages with 2-digit numbers. So, 9 pages with 1-digit numbers + 71 pages with 2-digit numbers = 80 pages.

40 & 41
They are 44 and 45.

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.
52 and 53
42 and 43 because 42*43 = 1806
Let the page numbers be x and x+1. The product of two consecutive numbers is x(x+1). Given that the product is 4160, we have the equation x(x+1) = 4160. By solving this quadratic equation, we find that the page numbers are 64 and 65.
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.
