Direction: The pie-chart provided below gives the distribution of land (in a village) under various food crops. Study the pie-chart carefully and answer the questions.
-
If 10% of the land reserved for rice be distributed to wheat and barley in the ratio 2 : 1, then the angle corresponding to wheat in the new pie-chart will be:
-
- 38.4°
- 76.8°
- 75.6°
- 45.5°
Correct Option: B
From above given chart ,
Corresponding angle for wheat is represented by 72°
10% of 72° = 7.2°
Ratio of wheat and barley = 2 : 1
∴ Increase in the corresponding angle of wheat
| = | 2 | x 7.2 = 4.8° |
| 3 |
∴ New corresponding angle for wheat = Old corresponding angle for wheat + Increase in the corresponding angle of wheat
= 72° + 4.8° = 76.8°
