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.
-
What is the percentage of donors having blood group ‘AB’?
-
- 61%
- 26%
- 16%
- 36%
Correct Option: C
On the basis of given pie chart in question ,
The corresponding angle of blood group ‘AB’ donors = 57.6°
The corresponding angle of all blood group donors = 360°
As we know that , 360° ≡ 100%
| ∴ 1° ≡ | % | 360 |
| ∴ 57.6° ≡ |  | 57.6 × 100 |  | % = = 16% | |
| 360 |
