The given pie chart shows the percentage of students enrolled for the courses A, B, C, D and E in a university and the table shows the percentage of students that passed out of the enrolled students.
| Courses | % passed out |
| A | 76 |
| B | 82 |
| C | 80 |
| D | 90 |
| E | 75 |
If the total number of students is 60000, then the total number of students who did not pass in the courses A,C is:
Answer & explanation
Correct answer: option 2
Total number of students = 60000
Number of students in A = \(\frac{18 }{100}\) × 60000 = 10800
Number of failed students = Total number of students - Number of passed students
Number of failed students in A = \(\frac{100-76 }{100}\) × 10800
= \(\frac{24 }{100}\) × 10800
= 2592
Number of students in C = \(\frac{20 }{100}\) × 60000 = 12000
Number of failed students in A = \(\frac{100-80 }{100}\) × 12000
= \(\frac{20 }{100}\) × 12000
= 2400
Total number of failed students in A and C = 2592 + 2400 = 4992
