A 58 Correct Answer Incorrect Answer
B 62(2/3) Correct Answer Incorrect Answer
C 64 Correct Answer Incorrect Answer
D 67 Correct Answer Incorrect Answer

Solution

Total number of students = 1100 + 700 = 1800
Number of students passed = (42% of 1100 + 30% of 700) - (462 + 210) = 672.
Number of failues = 1800-672 = 1128.
Percentage failure = (1128/1800) × 100 = 62(2/3)%.
