Let the page on the left be ' X '. Then the right-hand page is " X + 1'.
Thus x ( x + 1 ) = 2550 = [ X squared ] plus X
Try making X = 50.
50 x 50 = 2500
Then ( 50 x 50 ) + 50 would equal 2550
Since this is true, then the pages must be numbered 50 & 51
The book is opened to pages 26, on the left, and 27, on the right. The product of 26 times 27 is 702.

I guess this is best solved by trial and error. Try to multiply two consecutive numbers; if the product is too low, try higher number, if the product is too high, try lower numbers. For example, 20 x 21 = 420; since this is too low, your numbers are higher than that; 30 x 31 = 930; since this is too high, your numbers are lower than that.I guess this is best solved by trial and error.

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!

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.
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.

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.
Simple!A x B = 210Think:If 10 x 10 = 100 and 20 x 20 = 400 than the closest is 15 x 15 = 225So, if we used 15 multiplication.Take (225-210= 15)So, the answer is14 x 15 = 210The answer is page 14 and 15. :)Answer provided by Elson Ng
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.

They are 44 and 45.
The problems facing you are 1) As a student you are just facing what you don't know or what you know but don't know the in depth of it 2) The ability to assimilate all that is new to you might be a bit difficult
