answered-by-expert Expert Answer

It is clear that the number of sheets and their corresponding weight vary directly.

Also 1 kg = 1000 grams.

Writing the information in the table, we have


Number of sheets

5

x

Weight (in grams)

20

1000

Now, in case of direct variation the ratio remains constant, so we have

Hence, number of sheets are 250.
