Which section has the minimum failure rate in half yearly examination? |
| Answer» Total number of failures in half-yearly exams in a section = [ (Number of students failed in both exams) + (Number of students failed in half-yearly but passed in Annual exams) ] in that section Failure rate in half-yearly exams in Section A = Number of students of Section A failed in half-yearly x 100 % Total number of students in Section A = (28 + 14) x 100 % (28 + 14 + 6 + 64) = 42 x 100 % 112 = 37.5%. Similarly, failure rate in half-yearly exams in: Section B (23 + 12) x 100 % = 35 x 100 % = 32.71%. (23 + 12 + 17 + 55) 107 Section C (17 + 8) x 100 % = 25 x 100 % = 31.25%. (17 + 8 + 9 + 46) 80 Section D (27 + 13) x 100 % = 40 x 100 % = 30.53%. (27 + 13 + 15 + 76) 131 Clearly, the failure rate is minimum for Section D. | |
