Question

The cost price of 10 oranges is equal to the selling price of 9 oranges. What is the profit percentage?

• A. $11\frac{1}{9}\%$
  
• B. $12\frac{1}{7}\%$
  
• C. $10\frac{1}{6}\%$
  
• D. $12\frac{1}{9}\%$
  

Answer 1

The correct option is A $11\frac{1}{9}\%$


Assume the CP of 1oranges as Rs. 1
So CP of 10 oranges = Rs.10
SP of 9 oranges = Rs.10
So the SP of 10 oranges
$=\frac{10}{9}\times 10=\frac{100}{9}$
$\mathrm{Hence}\mathrm{Profit}\%=\frac{\frac{100}{9}-10}{10}\times 100=11\frac{1}{9}\%$
