Show answer & explanation

Correct answer: A

1. Calculate the total number of students in each department by adding all four columns in their respective rows. 2. Find the percentage of students passing both exams: (Passed both / Total) * 100. 3. Dept A: Total = 8 + 12 + 10 + 20 = 50. Percentage = (20 / 50) * 100 = 40%. 4. Dept B: Total = 16 + 10 + 12 + 22 = 60. Percentage = (22 / 60) * 100 = 36.67%. 5. Dept C: Total = 10 + 15 + 20 + 25 = 70. Percentage = (25 / 70) * 100 = 35.71%. 6. Dept D: Total = 10 + 18 + 22 + 30 = 80. Percentage = (30 / 80) * 100 = 37.5%. 7. Comparing the percentages, Department C (35.71%) has the minimum percentage. Final Answer: Option A
