Various Expenditures (in percentage) Incurred in Publishing a Book

Q1:

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%?

A Rs. 152.50

B Rs. 157.50

C Rs. 162.50

D Rs. 167.50

ANS:B - Rs. 157.50

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 .
