Exercise : Pie Charts - Pie Chart 1
Directions to Solve

The following pie-chart shows the percentage distribution of the expenditure incurred in publishing a book. Study the pie-chart and the answer the questions based on it.

Various Expenditures (in percentage) Incurred in Publishing a Book

6.
If the difference between the two expenditures are represented by 18° in the pie-chart, then these expenditures possibly are
Binding Cost and Promotion Cost
Paper Cost and Royalty
Binding Cost and Printing Cost
Paper Cost and Printing Cost
Answer: Option
Explanation:

Central angle of 18° = ( 18 x 100 ) % of the total expenditure
360

= 5% of the total expenditure.

From the given chart it is clear that:

Out of the given combinations, only in combination (d) the difference is 5% i.e.

Paper Cost - Printing Cost = (25% - 20%) of the total expenditure
= 5% of the total expenditure.

7.
For an edition of 12,500 copies, the amount of Royalty paid by the publisher is Rs. 2,81,250. What should be the selling price of the book if the publisher desires a profit of 5%?
Rs. 152.50
Rs. 157.50
Rs. 162.50
Rs. 167.50
Answer: Option
Explanation:

Clearly, S.P. of the book = 105% of C.P.

Let the selling price of this edition (of 12500 books) be Rs. x.

Then, 15 : 105 = 281250 : x     =>     x = Rs. ( 105 x 281250 ) = Rs. 1968750.
15

Therefore S.P. of one book = Rs. ( 1968750 ) = Rs. 157.50 .
12500

8.
If for an edition of the book, the cost of paper is Rs. 56250, then find the promotion cost for this edition.
Rs. 20,000
Rs. 22,500
Rs. 25,500
Rs. 28,125
Answer: Option
Explanation:

Let the Promotion Cost for this edition be Rs. p.

Then, 25 : 10 = 56250 : p     =>     p = Rs. ( 56250 x 10 ) = Rs. 22,500.
25

9.
Which two expenditures together have central angle of 108°?
Binding Cost and Transportation Cost
Printing Cost and Paper Cost
Royalty and Promotion Cost
Binding Cost and Paper Cost
Answer: Option
Explanation:

Central angle of 108° = ( 108 x 100 ) % of the total expenditure
360

= 30% of the total expenditure.

From the pie chart it is clear that:

Binding Cost + Transportation Cost = (20% + 10%) of the total expenditure
= 30% of the total expenditure.

Therefore Binding Cost and Transportation Cost together have a central angle of 108°.
