Answer:
<h2><em><u>23</u></em><em><u> </u></em><em><u>days</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>,</u></em>
No. of days taken by Jenny to read 7 books
= 8
<em><u>So</u></em><em><u>,</u></em>
No. of days taken by her to read 1 book

<em><u>Therefore</u></em><em><u>,</u></em>
No. of days taken by her to read 20 books

- <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

- <em>[</em><em>On</em><em> </em><em>dividing</em><em>]</em>
= 22.85.....
- <em>[</em><em>On</em><em> </em><em>approximating</em><em>]</em>
= 23 days (approx. )
<em><u>Hence</u></em><em><u>,</u></em>
<em><u>Jenny</u></em><em><u> </u></em><em><u>will</u></em><em><u> </u></em><em><u>take</u></em><em><u> </u></em><em><u>23</u></em><em><u> </u></em><em><u>days</u></em><em><u> </u></em><em><u>to</u></em><em><u> </u></em><em><u>read</u></em><em><u> </u></em><em><u>20</u></em><em><u> </u></em><em><u>books</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
We can write out a formula in order to solve this. Since sum represents addition, if x represents the unknown number, we can write the formula: x+51=-21. Then, to solve for x, you would subtract 51 from both sides to get x=-72 which is the final answer.
