If 5500 copies are published and the transportation cost on them amounts to Rs. 82500, then what should be the selling price of the book so that the publisher can earn a profit of 25%?
Answer: Option
Explanation:
For the publisher to earn a profit of 25%, S.P. = 125% of C.P.
Also Transportation Cost = 10% of C.P.
Let the S.P. of 5500 books be Rs. x.
Then, 10 : 125 = 82500 : x  x = Rs. |
 |
125 x 82500 |  |
= Rs. 1031250. |
| 10 |
 S.P. of one book = Rs. |
|
1031250 | |
= Rs. 187.50 . |
| 5500 |

Why we are adding 25% profit with 100% and why not with transport cost?

Here transportation cost is given 10%.
Therefore, the cost of one book is (b * 10)/100 = 0.1 * b.
Now given that 5500 * 0.1 * b = 82500.
Therefore, b = 150.
Now publisher needs 25% more profit hence, (150*25)/100 = 37.5,
Hence we add the final cost price for one book is 150+37.5 = 187.50.
Therefore, the cost of one book is (b * 10)/100 = 0.1 * b.
Now given that 5500 * 0.1 * b = 82500.
Therefore, b = 150.
Now publisher needs 25% more profit hence, (150*25)/100 = 37.5,
