# Read the pie-chart and answer the questions :

**Directions (Question Nos. 1 to 5):** The following pie-chart shows the percentage distribution of the expenditure incurred in publishing a book. Read the pie-chart and answer the questions.

- Royalti on the book is less than the printing cost by:

(a) 20% (b) 5% (c) 25% (d) 33 1/3 % - If for a certain quantity of books, the publisher has to pay Rs. 30600 as printing cost, then the amount of royalty cost to be paid for these books is:

(a) Rs.21200 (b) Rs. 19450 (c) Rs.22950 (d) Rs.26150 - If 5500 copies are published and the transportation cost on them amount to Rs.82500, then the selling price of the book so that the publisher can earn a profit of 25% is:

(a) Rs.175 (b) Rs.180 (c) Rs.187.50 (d) Rs.191.50 - The central angle of the sector corresponding to the expenditure incurred on Royalty is:

(a) 54^{o}(b) 24^{o}(c) 15^{o}(d) 48^{o}

**Answer: (b) 5%****Explanation:-**

The percentage of royalti cost = 15%

The percentage of printing cost = 20%Then, Royalty on the book is less than the printing cost = 20 – 15

= 5%Hence, the correct answer is option (b) 5%.

**Answer: (c) Rs. 22950****Explanation:-**

The publisher has to pay as printing cost = Rs. 30600

then the amount of royalty cost to be paid for these book = 30600 x 15/20

= Rs. 22, 950

Hence, the correct answer is option (c) Rs.22950.**Answer: (c) Rs. 187.50****Explanation:-**

The transportation cost of 5500 copies = Rs.82500

Then the transportation cost of 1 copies = 82500/5500

= Rs. 15

Total expenditure on a book = 15 x 100/10

= Rs.150

The publisher can earn a profit of 25%.

Then selling price of the book = 150 x 125/100

= Rs. 187.50Hence, the correct answer is option (c) Rs.187.50.

**Answer: (a) 54 degree****Explanation:-**

The percentage of Royalty cost = 15%

Then center angle of the sector corresponding to the expenditure incurred on royalty = 15 x 360/100

= 3 x 36/2

= 3 x 15

= 54 degreeHence, the correct answer is option (a) 54 degree.
