Answer 2

Answer:

84 % students are passed exam .

Step-by-step 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 = $\frac{passed\ student}{Total\ student}*100$.

Plug the values

Percentage of passed student = $\frac{21}{25}*100$.

Percentage of passed student = 21 * 4 .

Percentage of passed student = 84 % .

Therefore,  84 % students are passed exam .
