If the weight of five sheets of paper is 20 g, how many sheets of the same paper would weight 2.5kg...



​

Answer 1

$\rule{300}{2}$

$\huge\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R:-}}}}$

Given, Weight of 5 sheets of paper= 20g

Then, Weight of 1 sheet of paper= 20/5= 4g

Now,

No. of papers required to have the weight of 2.5kg or 2500g

= $\frac{Required\:Weight}{Weight\:of\:1\:Sheet}$

= $\frac{2500g}{4g}$

= ${625}$

Hence, 625 sheets would weight 2.5kg

This is the best possible answer

Answer 2

Answer:

weightof sheets 20g 2500g

no.of sheets 5 x

thia is case of direct variation

2500/× = 20/5

2500/x=4/1

it will cross multiply

4x=2500

x=2500/4

x=625 sheets
