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%?
Answer: Option
Explanation:
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 |
 S.P. of one book = Rs. |
|
1968750 | |
= Rs. 157.50 . |
| 12500 |

Profit = 5% of C.P.
S.P = 5%+100% = 105%.
S.P = 5%+100% = 105%.

Let the total cost price be Rs.X. royalty in the pie chart is 15% of X. T
Therefore (15X/100)=281250. Hence X= Rs.1875000.
The cost price (C.P) of a single copy is 1875000/12500 = Rs.150, (where 12500 is the total number of copies given in the question).
Again the publisher desires a profit of 5% of C.P. therefore selling price of single copy (S.P)= C.P+ profit=C.P+ (5%C.P)= 150+(150*5/100)=150+7.5= Rs.157.50 (answer).
Therefore (15X/100)=281250. Hence X= Rs.1875000.
The cost price (C.P) of a single copy is 1875000/12500 = Rs.150, (where 12500 is the total number of copies given in the question).
Again the publisher desires a profit of 5% of C.P. therefore selling price of single copy (S.P)= C.P+ profit=C.P+ (5%C.P)= 150+(150*5/100)=150+7.5= Rs.157.50 (answer).

Dividing large numbers are not easy without calculator especially when you are working against time.

15% is the share of Royalty as per Pie Chart. RS 2,81,250 is the amount paid as Royalty (given in situation above).
Let cost be X then 15% of X = 281250, ie X = 1875000 (total cost for 12500 copies), 1875000/12500 = Rs 150/- Cost per copy now add 5% profit in cost ie. 157.50 (7.5 is the profit 5% of 150).
Let cost be X then 15% of X = 281250, ie X = 1875000 (total cost for 12500 copies), 1875000/12500 = Rs 150/- Cost per copy now add 5% profit in cost ie. 157.50 (7.5 is the profit 5% of 150).
