Option : B
Explanation :
Total marks in the test = 100
For multiple choice questions = 3 marks
For essay questions = 11 marks
Option (A)
Marks for multiple choice questions = 12 × 3 = 36
Marks for essay type questions = 100 – 36 = 64
64 is not divisible by 11
∴ Option (A) is not correct.
Option (B)
Marks for multiple choice questions = 15 × 3 = 45
Marks for essay type questions = 100 – 45 = 55/11 = 11
Essay type questions are 5 No’s
∴ Option (B) is correct
Option (C)
Marks for multiple choice questions = 18 × 3 = 54
Marks for essay type questions = 100 – 54 = 46
46 is not divisible by 11
∴ Option (C) is not correct.
Option (D)
Marks for multiple choice questions = 19 × 3 = 57
Marks for essay type questions = 100 – 57 = 43
46 is not divisible by 11
∴ Option (D) is not correct.
