Question

Reenu types 540 words during half an hour. How many words would she type in 8 minutes?

Answer 1

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.
$$\begin{gathered} \mathrm{Now},\frac{540}{30}=\frac{x}{8} \\ \Rightarrow x=\frac{540\times 8}{30} \\ \Rightarrow x=144 \end{gathered}$$

Therefore, Reenu will type 144 words in 8 minutes.
