Directions: Study the given histogram that shows the marks obtained by students in an examination and answer the following question.
If the total marks obtained by students are represented as a pie chart, then the central angle corresponding to marks 250 or more but less than 300 is:
(correct the nearest degree)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 88°.
Total number of students = 30 + 45 + 60 + 35 + 40 + 35 = 245
Number of students corresponding to marks 250 or more but less than 300 = 60
Central angle = Number of students corresponding to marks 250 or more but less than 300/Total number of students × 360
Central angle = 60/245 × 360 = 8.1 or 88°
