Question

10. The total weight of an engineering entrance book of physics is 1.756 kg. If there are 625 pages in the book,
find the weight of each page. Also find the weight of the book, if 375 pages are added to the book.​

Answer 1

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
