When you open the book you see two adjacent pages. Let the smaller of the two page numbers be x.
Then x*(x+1) = 600. This solves to x = 24 and the other page is 25.
They are pages 42 and 43 because the product of both numbers is 1806
52 and 53
654798712386789
166 & 167
The page numbers would be 166 and 167.
The page numbers would be 183 and 184.
42 and 43 because 42*43 = 1806
168 and 169
The answer is 74 and 75
The two page numbers are 64 and 65. 64 x 65 = 4160.
The book is opened to pages 26, on the left, and 27, on the right. The product of 26 times 27 is 702.
if we call the first page A and the second page B we know that B = A+1 And if we multiply A by A+1 we get A2 + A. So, we want to find the square root of A... and the only clue we have is that it is close to 272 The square root of 272 = 16.4924. The number of the right hand page of a book is always the odd one. So we can try 16 and 17, and we see instantly that 16 x 17 = 272.
