Answer 1

Answer:

21%

Step-by-step explanation:

cost price of 11 chocolates = 10 rs

cost price of 1 chocolate = 10/11

selling price of 10 chocolates = 11 rs

selling price of 1 chocolate = 11/10

profit = sp - cp

         = 11/10 - 10/11

         = 21/110

profit % = profit /cp (100)

                 21/110 (11/10)(100)

                   =21%
