Let number of books by astrid's = x

Out of x , 84% are fiction.

So, Number of non fictional books = x - $\frac{84x}{100}$

= $\frac{100x- 84 x}{100} = \frac{16x}{100}$

→Ratio of number of books to fictional books

$=\frac{x}{\frac{84x}{100}}\\ = \frac{100}{84}\\= \frac{25}{21}$ ⇒[Dividing numerator and denominator by 4.]

→Out of 25 books by astrid 21 are fictional.

→ Number of fictional books by astrid = $\frac{21}{25}$

Answer:

"85.7%" is the right answer.

Step-by-step explanation:

According to the question,

The total capacity of water tank will be:

⇒ $v_1=A\times 14$

The total volume of water will be:

⇒ $v_2=A\times 12$

Now,

The percentage of total capacity will be:

= $\frac{100\times v_2}{v_1}$

= $\frac{v_2}{v_1}\times 100$

By putting the values, we get

= $\frac{A\times 12}{A\times 14}\times 100$

= $85.7$ %
