Study the graph carefully and answer the question given below:

If 5500 copies are published and miscellaneous expenditure on them amount to Rs. 5544 and the publisher earns a profit of 25%, then marked price of each copy is

• A. Rs. 25.20
• B. Rs. 37.50
• C. Rs. 31.50
• D. Rs. 30

Answer 1

The correct option is C Rs. 31.50

$LetthetotalchargesbeRs.x$

$Then,$

$4:100::5544:xorx$

$=\left(\frac{18\times 5444}{4}\right)=Rs.138600$

$\therefore \text{Total cost}=Rs.138600$

$\therefore \text{Cost price of each copy}$

$=Rs.\left(\frac{138600}{5500}\right)=Rs.25.20$

$\therefore \text{Marked price}=125\%ofRs.25.20$

$=Rs.(\frac{125}{100}\times 25.20)=Rs.31.50$
