Examination Passing Criteria Analysis
To determine which student(s) passed, we need to evaluate their performance against the set criteria.
Calculate Passing Thresholds
- Total Maximum Marks: Examination A (30 marks) + Examination B (70 marks) = 100 marks.
- Minimum Total Percentage Required: 40% of 100 marks = $0.40 \times 100 = 40$ marks.
- Minimum Marks in Examination B Required: 40% of 70 marks = $0.40 \times 70 = 28$ marks.
Student Marks Evaluation
The passing requirements are: total marks $\ge$ 40 AND marks in B $\ge$ 28.
| Student | Marks in A (out of 30) | Marks in B (out of 70) | Total Marks (out of 100) | Pass Criteria Met? (Total $\ge$ 40 AND B $\ge$ 28) |
| $S_1$ | 12 | 28 | $12 + 28 = 40$ | Yes (40 $\ge$ 40 AND 28 $\ge$ 28) |
| $S_2$ | 10 | 29 | $10 + 29 = 39$ | No (Total 39 < 40) |
| $S_3$ | 16 | 27 | $16 + 27 = 43$ | No (B 27 < 28) |
| $S_4$ | 0 | 29 | $0 + 29 = 29$ | No (Total 29 < 40) |
Conclusion on Passing Students
Based on the evaluation:
- $S_1$ meets both criteria (Total = 40, B = 28).
- $S_2$ fails because the total marks (39) are less than 40.
- $S_3$ fails because the marks in B (27) are less than 28.
- $S_4$ fails because the total marks (29) are less than 40.
Therefore, only student $S_1$ has passed the course.
