Question

Two computers were purchased for rs 16000 each. One was sold at gain of 5 percent and the other at a loss of 4 percent. Find the overall gain or loss percent in the whole transactions

Answer 1

Total CP = 32000

CP of 1st = 16000

Profit % = 5%

Profit = 5/100*16000

          = 800

SP of 1st = CP + Profit

               = 16000 + 800

                = 16800

CP of 2nd = 16000

Loss % = 4%

Loss = 4/100*16000

         = 640

SP of 2nd = CP - Loss

                   = 16000 - 640

                    = 15360

Total SP = 32160

As SP>CP = Profit

Profit = 160

Profit % = P/CP*100

             = 160 / 32000*100

            = 0.5 % profit
