Answer 2

Given ,

12 sheets of the thick paper weigh 40 grams

How many sheets would weigh 1kg

We know that 1kg = 1000gms

12 sheets = 40 grams

? sheets = 1000 grams

[cross multiplication]

$= \frac{12 \times 1000}{40} \\ \\ = \frac{12000}{40} \\ \\ = 300 \: sheets$

Therefore 300 sheets would weigh 1kg !
