The following pie charts show the data of the number of appeared and passed students of class 12 in sections A, B, C, D and E.
How many students failed in Section C?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 300.
The total angle of a pie chart = 360º
so the percentage of students in Section C = 100/360 × 100 = 27.78%
The total number of students who appeared = 1800
so the number of students who appeared in Section C = 27.78/100 × 1800 = 500
The total number of passed students = 800
so the number of students who passed in Section C = 25/100 × 800 = 200
The number of students who failed in Section C = 500 − 200 = 300
