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
Solution:
(c) 300
Let x sheets weigh 1 kg.
Now, 1 kg = 1000 g
| No. of sheets | 12 | |
| Weight (in g) | 40 | 1000 |
Now,$\frac{12}{40}=\frac{x}{1000}$
$\Rightarrow x=\frac{12 \times 1000}{40}$
$\Rightarrow x=300$
