Question

Tick (✓) the correct answer:
The weight of 12 sheets of a thick paper is 40 grams. How many sheets would weight 1 kg?
(a) 480
(b) 360
(c) 300
(d) none of these

Answer 1

(c) 300
Let x sheets weigh 1 kg.
Now, 1 kg = 1000 g

No. of sheets	12	$x$
Weight (in g)	40	1000

$$\begin{gathered} \mathrm{Now},\frac{12}{40}=\frac{x}{1000} \\ \Rightarrow x=\frac{12\times 1000}{40} \\ \Rightarrow x=300 \end{gathered}$$
