1. 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%.

2. 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.

3. 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. 187.50

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

4. 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 degree

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