Various Expenditures (in percentage) Incurred in Publishing a Book
For an edition of 12,500 copies, the amount of Royalty paid by the publisher is Rs. 281,250. 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
Correct answer is B
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)/15 ) = Rs. 1968750
Therefore S.P. of one book = Rs. ( 1968750/12500 ) = Rs. 157.50
