Marks: +1, -0

If the weight of 18 sheets of paper is 50 grams, how many sheets of the same paper will weight

3 3/ 4

kg ?

Solution:

Let total no. of sheets = x
The weight of 18 sheets of paper = 50g
The weight of 1 sheet of paper

=50/18g

The weight of x sheets of paper

=50/18xg

According to question

\;\;{50}/{18}x=3\;\;{3}/{4}×100{g}

⇒\;\;{50}/{18}x=\;\;{15}/{4}×1000

x=\;\;{15×18×1000}/{4×50}

=1350
