• A. 250
• B. 240
• C. 194
• D. 195

Answer 1

Answer:

B. 240

Given:

Kachita's attendance in her school for academic session 2018- 2019 was 216 days.

Kachita's attendance % = 90%

Formula

x as a percentage of y = $\frac{x}{y}\times{100}$

 

Calculation:

Let total working days of the school were x days, then

$x\times(\frac{90}{100})$ = 216

⇒ x = 216$\times(\frac{100}{90})$

⇒ x = 240 days.

∴ Total working days of the school were 240 days.
