The given parameters;
- number of the males, = 85
- number of the females, = 30
- percentage of the female that passed = 40%
- percentage of the male that passed, = 20%
To find:
- the percentage of students that passed the exam
The number of the male students that pass the exam;
[tex]= 0.2 \times 85 \\\\= 17[/tex]
The number of the female students that pass the exam;
[tex]= 0.4 \times 30 \\\\= 12[/tex]
The total number of students in the school;
= 85 + 30
= 115
The total number of the students that passed the exam;
= 17 + 12
= 29
The percentage of students that passed the exam;
[tex]= \frac{total \ number \ that \ passed }{total \ number \ of \ the \ students} \times 100\% \\\\= \frac{29}{115} \times 100\%\\\\= 25.2 \%[/tex]
