Mark (✓) against the correct answer:

Rashmi types 510 words in half an hour. How many words would she type in 10 minutes?

(a) 85

(b) 150

(c) 170

(d) 153


(c) 170 words

Let x be the number of words typed by Rashmi in 10 minutes.

Less time will be taken to type less number of words.

So, it is a case of direct variation.

Now, $\frac{510}{30}=\frac{x}{10}$

$\Rightarrow x=170$

∴ Rashmi will type 170 words in 10 minutes.
