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.
10x=9y
x=9y10
Hence, selling price is more than cost price.
So, there will be profit.
Profit = S.P - C.P
=(y9y10)
=y10

Profit % =ProfitC.P×100

=y109y10× 100

=19×100
=11.11%
Hence, the profit percentage is 11.11%.
