Direction: This is a pie-chart for the data on A, B, O, AB blood groups of 150 donors. Observe the pie-chart and answer the questions.
-
The number of persons having either blood group ‘A’ or blood group ‘B’ is :
-
- 84
- 96
- 78
- 54
Correct Option: A
As per the given pie chart in question ,
Total number of A, B, O and AB blood groups of donors = 150
The corresponding angle of blood group ‘B’ donors = 129.6°
The corresponding angle of blood group ‘A’ donors = 72°
The corresponding angle of all blood group donors = 360°
| Persons with blood group A or B = | × 150 | 360 |
| Persons with blood group A or B = | = 84 | 360 |
