Question:
Reenu types 540 words during half an hour. How many words would she type in 8 minutes?
Solution:
Let Reenu type x words in 8 minutes.
| No. of words | 540 | x |
| Time taken (in min) | 30 | 8 |
Clearly, less number of words will be typed in less time.
So, it is a case of direct proportion.
Now, $\frac{540}{30}=\frac{x}{8}$
$\Rightarrow x=\frac{540 \times 8}{30}$
v
Therefore, Reenu will type 144 words in 8 minutes.
