Question

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%?

• A. Rs. 187.50
• B. Rs. 191.50
• C. Rs. 175
• D. Rs. 180

Answer 1

The correct option is A Rs. 187.50

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.
The, 10:125=82500:x
$\Rightarrow x=Rs.\left(\frac{25\times 82500}{10}\right)=Rs.1031250.$
$\therefore$ S.P of one book =Rs.$\left(\frac{1031250}{5500}\right)=Rs.187.50$
