Hello I don't really know how to do this question, can someone PUH-LEASE help me??


The Question is as follows:

Hi,

This is another square number style question. When Ken opens his book, we known that the two pages are sequential ie pages 10 and 11 or 21 and 22, etc. Also product means multiple so we can write this like
--> Left Page x Right Page = 600
--> What square number is near 600?
--> 25x25=625,
--> try 24x25 --> 600

So Ken is looking at pages 24 and 25.
