According to given pie chart in question ,
Percentage of printing cost = 20%
Percentage of Royalty cost = 15%
Printing cost = $ 30600
∵ 20% ≡ $ 30600∴ 1% ≡ 30600 20 ∴ Required paid amount = Printing cost × Percentage of Royalty cost Percentage of printing cost
Correct Option: C
According to given pie chart in question ,
Percentage of printing cost = 20%
Percentage of Royalty cost = 15%
Printing cost = $ 30600
∵ 20% ≡ $ 30600∴ 1% ≡ 30600 20 ∴ Required paid amount = Printing cost × Percentage of Royalty cost Percentage of printing cost ∴ Required paid amount = 30600 × 15 = $ 22950 20

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
