A 11.11% B 12.5% C 10% D 9.99% Open in App Solution

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.

∴ 10 x = 9 y x = 9 y 10

Hence, selling price is more than cost price.

So, there will be profit.

Profit = S.P - C.P = ₹ ( y − 9 y 10 ) = ₹ y 10 P r o f i t % = P r o f i t C . P × 100 = y 10 9 y 10 × 100 = 1 9 × 100 = 11.11 %

Hence, the profit percentage is 11.11%.
