$\bf\huge\underline{Answer}$

The total number of days the school was opened is 240 respectively.

Explanation :-

Given :

No. of days Sonal attended school = 204

Percentage = 85 %

To find :

The number of days school opened.

Solution :

Let the total no. of days the school opened be x

According to question,

$= > 85 \% \: of \: x = 204$

$= > \dfrac{85}{100} \times x = 204$

$= > \dfrac{85x}{100} = 204$

$= > x = \dfrac{204 \times 100}{85}$

$= > x = 240$

Hence, the number of days the school opened is 240

Verification :-

Putting the value of x

$= > \dfrac{85}{100} \times 240 = 204$

$= > \dfrac{20400}{100} = 204$

$= > 204 = 204$

Therefore, L.H.S = R.H.S

Hence, Proved.
