Ranking Students by PCBM Marks
To determine which student gets the 3rd rank based on total marks in PCBM, we first need to calculate the total marks for each student.
Marks Table
| Student | P | C | B | M |
| W | 70 | 90 | 50 | 85 |
| X | 55 | 80 | 95 | 60 |
| Y | 60 | 20 | 90 | 40 |
| Z | 90 | 80 | 40 | 65 |
Total Marks Calculation
The total marks for each student are calculated by summing their marks across the four subjects (P, C, B, M). The formula used is:
$ \text{Total Marks} = \text{Marks}_P + \text{Marks}_C + \text{Marks}_B + \text{Marks}_M $
- Student W: $70 + 90 + 50 + 85 = 295$ marks
- Student X: $55 + 80 + 95 + 60 = 290$ marks
- Student Y: $60 + 20 + 90 + 40 = 210$ marks
- Student Z: $90 + 80 + 40 + 65 = 275$ marks
Ranking Students
Students are ranked based on their total marks in descending order (highest total marks get the 1st rank).
| Rank | Student | Total Marks |
| 1st | W | 295 |
| 2nd | X | 290 |
| 3rd | Z | 275 |
| 4th | Y | 210 |
Conclusion
Based on the calculated total marks and the resulting ranks, student Z obtains the 3rd rank.
