Answer 2

Answer:

Step-by-step explanation:

concept Method

      given data-

1. buys means here cost price  so cp of an orange is 10/11.
2. sells means here selling price so sp of an orange is 11/10.  

        find-

       1. gian or loss percent

          here, cp<sp based on given data so we need to find gain%

       so, gain%= (sp-cp/cp)100

                              ((11/10 -10/11)/10/11)100

                             ( 11/10 *11/10-10/11*11/10)100

                             (  11*11-10*10)=21%
