Question

The weight of $12$ sheets of a thick paper is $40$ grams. How many sheets would weight $1kg$?

• A. $480$
• B. $360$
• C. $300$
• D. None of these

Answer 1

The correct option is C $300$

If there are more number of sheets then, the weight will also be more. Therefore it's directly proportional.

Let us consider the sheets be $x$, then

$12/0.01=x/1$

$0.04\times x=12\times 1$
$0.04x=12$
$x=12/0.01$

$x=300$

$\therefore 300$ sheets would weight $1kg$
