B Correct answer
Explanation

Number of boys who passed = 1200*40/100 = 480 Number of girls who passed = 800*30/100 = 240 Total number of students who passed = 480 + 240 = 720 Total number of students = 1200 + 800 = 2000 Percentage of passed students = 720*100/2000 = 36% So, the percentage of students who failed = (100 - 36)% = 64% Hence, this option is correct.
