The given table shows the number of students having various blood groups in a classroom.If this data is to be presented on a pie chart, the angle of sector for blood group B would be:
Correct answer: C. 144o
- A. 24o
- B. 90o
- C. 144o
- D. 270o
Explanation
To determine the angle of the sector for blood group B, calculate it using the formula: (Number of students with blood group B / Total number of students) × 360°.=6/15×360°=144°So option C is correct.A, B and D mentions wrong angles.
