    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.
