As per the given pie chart in question ,
Corresponding central angle for miscellaneous expenditure = 108°
∵ 360° ≡ 100%∴ 1° ≡ 100 % 360
Correct Option: D
As per the given pie chart in question ,
Corresponding central angle for miscellaneous expenditure = 108°
∵ 360° ≡ 100%∴ 1° ≡ 100 % 360 ∴ 108° ≡ 108 × 100 = 30% 360
Direction: The pie graph indicates the break-up of the cost of construction of a house. Assuming that the total cost of construction is $ 6,00,000, answer the following questions.

- The percentage of the total cost of construction spent on cement, steel and supervision is :
-

From the given pie chart in question ,
Corresponding angle for cement, steel and supervision = 72° + 54° + 54° = 180°∴ Required percent = Corresponding angle for cement, steel and supervision × 100 360°
Correct Option: A
From the given pie chart in question ,
Corresponding angle for cement, steel and supervision = 72° + 54° + 54° = 180°∴ Required percent = Corresponding angle for cement, steel and supervision × 100 360° ∴ Required percent = 180 ° × 100 = 50% 360°
- The amount spent on labour exceeds the amount spent on steel by :

On the basis of given pie chart in question ,
Corresponding central angles :
Labour ⇒ 90°
Steel ⇒ 54°
∴ Required excess amount = Corresponding central angle of Labour - Corresponding central angle of SteelCorrect Option: A
On the basis of given pie chart in question ,
Corresponding central angles :
Labour ⇒ 90°
Steel ⇒ 54°
∴ Required excess amount = Corresponding central angle of Labour - Corresponding central angle of Steel
∴ Required excess amount = 90° – 54° = 36° i.e. 10% of total cost.
- The amount spent on labour exceeds the amount spent on supervision by :

From the given pie chart in question ,
Corresponding central angles :
Labour ⇒ 90°
Supervision ⇒ 54°
Difference = Corresponding central angle of Labour - Corresponding central angle of Supervision
Difference = 90° – 54° = 36°Correct Option: C
From the given pie chart in question ,
Corresponding central angles :
Labour ⇒ 90°
Supervision ⇒ 54°
Difference = Corresponding central angle of Labour - Corresponding central angle of Supervision
Difference = 90° – 54° = 36°∴ Required excess amount = $ 36 × 600000 = $ 60000 360

According to given pie chart in question ,
Corresponding central angle for the cost on timber = 36°
Total cost of construction = $ 6,00,000
∵ 360° ≡ $ 600000∴
1° =600000 360
Correct Option: A
According to given pie chart in question ,
Corresponding central angle for the cost on timber = 36°
Total cost of construction = $ 6,00,000
∵ 360° ≡ $ 600000∴
1° =600000 360 ∴ 36° ≡ $ 600000 × 36 = $ 60000 360
