Question

16. In a class room, out of 35 students 28 students are present. How much percent of students are absent ? ​

Answer 1

Given: In a classroom out of $35$students, $28$students are present.

We have to find the percent of absent students.

We are solving in the following way:

We have,

The total number of students in the classroom is$35$, and $28$students are present.

So, the number of students absent are:

Total number of students -Total number of present students

$\Rightarrow 35-28\\\Rightarrow 7$

Hence, $7$students are absent.

So, the percent of absent students will be:

$\Rightarrow \frac{7}{35} \times 100\\\Rightarrow 20$

Hence, the percent of absent students is$20$%.

Answer 2

Answer:

$20$% students are absent.

Step-by-step explanation:

Given : Total number of students = $35$

           Number of present students = $28$  

To find : How much percent of students are absent ? ​

Solution :  

• It is given that total number of students = $35$

           Number of present students = $28$  

• We have to find the percentage of absent student.
• To find the percentage of absent students, we have to first find the number of absent students.
• ∴ Number of absent students = Total number of student - Total number     of present students              

                                           = $35-28$

                                           = $7$

• ∴ $7$ students are absent.
• Now to find the percentage of absent students, we have a formula,

                  % of absent student = $\frac{Absent students}{Total students} *100$

                                                = $\frac{7}{28} *100$

                                                = $\frac{1}{5} *100$

                                                = $20$%

• ∴  $20$% students are absent.
