On the basis of given pie chart in question ,
Percentage expense on royalty = 15%
Percent of total expenditure = 100%
Corresponding angle for total expenditure = 360°
∵ 100% ≡ 360°∴ Required angle = Corresponding angle for total expenditure × Percentage expense on royalty = 54° Percent of total expenditure
Correct Option: C

On the basis of given pie chart in question ,
Given that , Expenditure on clothes = Rs. 825.
The corresponding angle of total expenditure = 360°
The corresponding angle of expenditure on clothes = 36°
∵ 36° ≡ $ 825∴ Total monthly income = Expenditure on clothes × The corresponding angle of total expenditure The corresponding angle of expenditure on clothes
Correct Option: B
On the basis of given pie chart in question ,
Given that , Expenditure on clothes = Rs. 825.
The corresponding angle of total expenditure = 360°
The corresponding angle of expenditure on clothes = 36°
∵ 36° ≡ $ 825∴ Total monthly income = Expenditure on clothes × The corresponding angle of total expenditure The corresponding angle of expenditure on clothes ∴ Total monthly income = 825 × 360 = & 8250 36

As per the given pie chart in question ,
Total number of published copies = 5500
Transportation cost = 10%
Transportation cost = $ 82500
∵ 10% ≡ $ 82500
∴ 100% ≡ $ 825000∴ Cost for publishing 1 book = 825000 = $ 150 5500
Correct Option: B
As per the given pie chart in question ,
Total number of published copies = 5500
Transportation cost = 10%
Transportation cost = $ 82500
∵ 10% ≡ $ 82500
∴ 100% ≡ $ 825000∴ Cost for publishing 1 book = 825000 = $ 150 5500
For a profit of 25% ,∴ Required S.P. = 150 × 125 = $ 187.50 100
