Show answer & explanation
Correct answer: A
To find the year with the lowest average marks, calculate the sum of marks for all students in each year and divide by 5.
2021: (75 + 82 + 75 + 84 + 74) / 5 = 390 / 5 = 78
2022: (90 + 93 + 85 + 86 + 79) / 5 = 433 / 5 = 86.6
2023: (96 + 76 + 65 + 85 + 85) / 5 = 407 / 5 = 81.4
2024: (92 + 85 + 66 + 81 + 82) / 5 = 406 / 5 = 81.2
2025: (86 + 82 + 73 + 80 + 83) / 5 = 404 / 5 = 80.8
Comparing the averages, 78 is the lowest value. Therefore, the year 2021 witnessed the lowest average marks.
