Show answer & explanation
Correct answer: B
Identify the number of students who passed from schools A, C, and D: 175, 200, and 240.
Calculate their average: (175 + 200 + 240) / 3 = 615 / 3 = 205.
Identify the total number of students who appeared from school B: 250.
Calculate the percentage less: [(Appeared B - Average Passed A,C,D) / Appeared B] * 100 = [(250 - 205) / 250] * 100 = (45 / 250) * 100 = 18%.
Final Answer: Option 2
