Which section has the maximum success rate in annual examination?

Answer: Option

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.

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.

@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.
