• A. 11.11%
• B. 12.5%
• C. 10%
• D. 9.99%

Answer 1

The correct option is A 11.11%

Given that,
The cost price of 10 articles is equal to the selling price of 9 articles.
Let the cost price of one article be ₹ x and the selling price of one article be ₹ y.
$\therefore 10x=9y$
$x=\frac{9y}{10}$
Hence, selling price is more than cost price.
So, there will be profit.
Profit = S.P - C.P
$=₹(y-\frac{9y}{10})$
$=₹\frac{y}{10}$

$Profit\%=\frac{Profit}{C.P}\times 100$

$=\frac{\frac{y}{10}}{\frac{9y}{10}}\times 100$

$=\frac{1}{9}\times 100$
$=11.11\%$
Hence, the profit percentage is 11.11%.
