7.
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 |

So basically you can do
Royalty of 2,81,250 is 15% of C.P
Hence, 2,81,250÷3 = 93,750.
Now, 93,750*2 = 1,87,500 (10% of C.P of the book),
1,87500*10 = 18,75,000 (C.P of book),
18,75,000÷12,500 = 150÷5% = 7.5.
Hence, 157.5.
It may sound big but I did all these calculations within a minute.

@All.
First, here I tried to find 1%of royalty = 281250/15.
Amount of 1% of royalty=18750,
Here, I have to find 105 % amount after adding profit on sale=18750 * 105 = 1968750
So, the Selling price of a single copy = 1968750/12500
= 157.5.

15 ---- 281250 (royalty).
105 -------- 281250/15 x105 = 1968750 (sp).
SP of single copy = 1968750/12500 = 157.50.
105 -------- 281250/15 x105 = 1968750 (sp).
SP of single copy = 1968750/12500 = 157.50.
