Direction: The pie- chart given below shows the usage of materials in the construction of a house. Study the chart and answers the questions :
-
If the cost of cement is $ 5000, then the labour cost is :
-
- $ 5500
- $ 6250
- $ 9000
- $ 4000
Correct Option: B
From the given pie chart in question ,
The cost of cement = $ 5000
Corresponding angle for cement = 72°
Corresponding angle for labour expenses = 90°
∵ 72° ≡ $ 5000
| ∴ 1° = | 72 |
| ∴ 90% ≡ $ |  | 5000 | × 90° |  | = $ 6250 |
| 72° |
