Question

a class has 60 students.Given that 85% passed a science test. Find the number of students who failed and then convert o %

Answer 1

Given:

Total students = 60

Student passed = 85%

To find:

The number of students who failed and then convert it in %.

Solution:

We have,

Number of passed student = 85% of Total students

=
`(85)/(100)* 60`

=
`51`

So, number of passes students is 51.

Number of students who failed = Total students - Passes students

=
`60-51`

=
`9`

So, number of students who failed is 9.

`\text{Fail}\%=\frac{\text{Failed students}}{\text{Total students}}* 100`

`\text{Fail}\%=(9)/(60)* 100`

`\text{Fail}\%=15`

Therefore, 15% students fail in the test.
