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
= [tex]\dfrac{85}{100}\times 60[/tex]
= [tex]51[/tex]
So, number of passes students is 51.
Number of students who failed = Total students - Passes students
= [tex]60-51[/tex]
= [tex]9[/tex]
So, number of students who failed is 9.
[tex]\text{Fail}\%=\dfrac{\text{Failed students}}{\text{Total students}}\times 100[/tex]
[tex]\text{Fail}\%=\dfrac{9}{60}\times 100[/tex]
[tex]\text{Fail}\%=15[/tex]
Therefore, 15% students fail in the test.
