Total no of pages = 625 pages
Given : Weight of total pages of the book = 1.756 kg
Let x be the weight of one page.
So, 625*x = 1.756
x = 1.756/625 = 0.0028096kg
Weight of one page = 0.0028096kg
Now, given : Total no. Of pages = 625+375 = 1000 pages
Therefore, total weight of the book = total no. of pages * weight of one page = 1000* 0.0028096 = 2.8096Kg
