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 of the sector representing marks 200 or more but less than 300, is :
( correct to the nearest degree)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 154°.
Total marks = 30 + 45 + 60 + 35 + 40 + 35 = 245
Marks obtained by students which are 200 or more but less than 300 = 45 + 60 = 105
Central angle = Marks obtained/Total marks
Central angle = 105/245 × 360° = 154.28° or 154°
