Answer 2

84 % students are passed exam .

Explanation:

Given : If 25 students took an exam and 4 of them failed,

To find : what percent of them passed.

Solution : We have given

Total students = 25 .

Failed student = 4 .

Passed student = 25 - 4 = 21.

Percentage of passed student =
`(passed\ student)/(Total\ student)*100`.

Plug the values

Percentage of passed student =
`(21)/(25)*100`.

Percentage of passed student = 21 * 4 .

Percentage of passed student = 84 % .

Therefore, 84 % students are passed exam .
