Answer 1

Answer:

The gain percentage is 75%

Step-by-step explanation:

Given : CP of article = 4/7 of SP

           Loss or gain Percentage = ?

Solution : As the CP is less than SP, there is a profit.

So Profit percentage = 100 x (SP- CP)/CP

                                  =100x (SP-4/7SP)/4/7SP

                                  = 100 x SP(1-4/7)/4/7 SP

                                  = 100 x 3/7 ÷ 4/7

                                  = 100 x 3/4

                                 = 75 %
