Question

Ankit sold two jeans for rupees 990 each one on one he gain 10% gain and one other he lost 10% find his gain or loss percent in the whole transaction

Answer 1

Answer:

11.2% or 5.5%

Step-by-step explanation:

FOR ONE  JEANS :

Given: SP = 990

           GAIN% = 10

thus, to find : CP = ?

thus, CP = SP*100 / 100 + gain%

              = 990*100 / 100 + 10

              = 990*100 / 110

              = 900.

FOR SECOND JEANS :

Given : SP = 990

            Loss% = 10

thus, to find : CP = ?

thus, CP = SP*100 / 100 - loss%

              = 990*100 / 100 - 10

              = 990*100 / 90

              = 1100.

thus, Total CP = 1100 + 900

                        = 2000

Total SP = 990 + 990

              = 1890

thus, Total Loss = CP - SP

                 = 2000 - 1890

                 = 110

thus , Total Loss% = 110/2000 * 100

                               = 110 / 20

                                = 11/2% or 5.5 %
