A school has four sections A, B, C, D of Class IX students.

The results of half yearly and annual examinations are shown in the table given below.

 Result No. of Students Section A Section B Section C Section D Students failed in both Exams 28 23 17 27 Students failed in half-yearlybut passed in Annual Exams 14 12 8 13 Students passed in half-yearlybut failed in Annual Exams 6 17 9 15 Students passed in both Exams 64 55 46 76

4.

Which section has the maximum success rate in annual examination?

 [A]. A Section [B]. B Section [C]. C Section [D]. D Section

Explanation:

Total number of students passed in annual exams in a section

= [ (No. of students failed in half-yearly but passed in annual exams)

+ (No. of students passed in both exams)

] in that section Success rate in annual exams in Section A

 = No. of students of Section A passed in annual exams x 100 % Total number of students in Section A

 = (14 + 64) x 100 % (28 + 14 + 6 + 64)

 = 78 x 100 % 112

= 69.64%.

Similarly, success rate in annual exams in:

 Section B (12 + 55) x 100 % = 67 x 100 % = 62.62%. (23 + 12 + 17 + 55) 107

 Section C (8 + 46) x 100 % = 54 x 100 % = 67.5%. (17 + 8 + 9 + 46) 80

 Section D (13 + 76) x 100 % = 89 x 100 % = 67.94%. (27 + 13 + 15 + 76) 131

Clearly, the success rate in annual examination is maximum for Section A.

 Shadab Akhtar said: (May 5, 2016) @Sushant. Do You want to calculate it in minimum time? Just see the maximum number of students who have passed the annual examination. By seeing in each section you will know that section A has maximum no. of students i.e 14 , so the correct answer is 14.

 Harshitha said: (Dec 3, 2020) @Shadab. There is a correction we need to see students passed in annual and also 1/2 yearly failed but passed in annual is 14- for 1/2 yearly passed and 64- for the annual pass is highest for section A. Hence the answer.
