Question

If the weight of 12 sheets of thick paper is 40 grams, how many sheets of the same paper would weigh 2500 grams?​

Answer 1

For 12 sheets, weight of paper is 40 grams

Let number of sheets for 2500 is x.

Using direct proportion concept:

12/40 = x/2500

x=(12×2500)/40

x=750

Answer 2

Weight of one sheet=x

12x=40 g

x=40/12=3.33 g

total weight=5/2 kg=2.5 kg=2500 g

number of sheets=2500/3.33

=750 full sheets
