A class has four sections and the number of students in each section is 50, 40, 30 and 20. The pass percentage of these sections is 20%, 15%, 30%, and 50% respectively. The failure percentage of the entire class is?
- 70%
- 75%
- 80%
- None of these
Explanation
Total students = 50 + 40 + 30 + 20 = 140
Passed students:
Section 1: 50 _ 20% = 10
Section 2: 40 _ 15% = 6
Section 3: 30 _ 30% = 9
Section 4: 20 _ 50% = 10
Total passed = 10 + 6 + 9 + 10 = 35
Pass % of whole class = 35 / 140 * 100 = 25%
Failure % = 100% - 25% = 75%
