Answer 1

Answer:

90% present

27 absent. 27 is 10%

So no. of students present are 27 x 9 = 243

243 students were present

Step-by-step explanation:

Answer 2

Given,

Percentage of present students = 90%

Percentage of absent students = (100 - 90)% = 10%

Let the total number of students = x

So,

10% of total students = 27

$\implies 10\% \:of \:x = 27 \\ \implies 10\% \times x = 27 \\ \implies \dfrac{10}{100} \times x = 27 \\ \implies x = 27 \times \dfrac{100}{10}$

x = 270

Total number of students = 270 students

Number of students who attended school = Number of total students - Number of absent students

= 270 - 27

= 243 students

Therefore, 243 students attended school.
