Question

out of 40 students 8 are absent . what percent of student were absent?

Answer 1

total strength = 40

10 % of 40 = 4

so 20% of 40 =8

therefore 20% were absent and 80% were present.

Answer 2

Given:

Out of 40 students, 8 are absent.

To find:

The percent of students that were absent.

Solution:

The percent of students that were absent is 20℅.

We can find the answer by following these steps:

As given, we have,

The total number of students = 40

The number of students that were absent = 8

So,

the percent of students that were absent is equal to the ratio of the number of absent students to the total number of students and then multiplied by 100.

This means

$\% \: of \: absent \: students = \frac{number \: of \: absent \: students}{total \: number \: of \: students} \times 100$

$= \frac{8}{40} \times 100$

On solving the above, we get

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

$= 20\%$

Hence, the percentage of absent students is 20℅.
