Show answer & explanation
Correct answer: D
First, calculate the total marks for each student over the five years.
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
Combined marks for A and B = 439 + 418 = 857
Combined marks for C and D = 364 + 416 = 780
The difference in marks is 857 − 780 = 77
The percentage increase relative to the total marks of C and D is: (77 / 780) * 100 ≈ 9.87% = 10%
