The following table gives the marks (out of 100) of five students (i.e. A, B, C, D and E) over the years 2021 to 2025.STUDENTS NAME Year A B C D E 2021 75 82 75 84 74 2022 90 93 85 86 79 2023 96 76 65 85 85 2024 92 85 66 81 82 2025 86 82 73 80 83
Calculate Cumulative Marks for Each Student
To find the student with the maximum cumulative marks from 2021 to 2025, we need to sum the marks obtained by each student over these five years.
The table shows the marks for each student:
| STUDENT NAME | 2021 | 2022 | 2023 | 2024 | 2025 |
|---|---|---|---|---|---|
| A | 75 | 90 | 96 | 92 | 86 |
| B | 82 | 93 | 76 | 85 | 82 |
| C | 75 | 85 | 65 | 66 | 73 |
| D | 84 | 86 | 85 | 81 | 80 |
| E | 74 | 79 | 52 | 82 | 83 |
Determine Total Scores
Sum the marks for each student:
- Student A: $75 + 90 + 96 + 92 + 86 = 439$
- Student B: $82 + 93 + 76 + 85 + 82 = 418$
- Student C: $75 + 85 + 65 + 66 + 73 = 364$
- Student D: $84 + 86 + 85 + 81 + 80 = 416$
- Student E: $74 + 79 + 52 + 82 + 83 = 370$
Identify Maximum Cumulative Score
Compare the total scores calculated above:
- Student A: 439
- Student B: 418
- Student C: 364
- Student D: 416
- Student E: 370
The highest cumulative score is 439, which belongs to Student A.
