Question

Mr mehta purchased a video for Rs 20000 and a television for Rs 30000. on the video he lost 5% and on the television he gained 8%. find his total gain or loss per cent?

Answer 1

Video=>
CP=20000
loss=5*20000/100
       = 1000
SP=20000-1000
     =19000

TV=>
CP=30000
loss=8*30000/100
       = 2400
SP=30000+2400
     =32400

therefore,
total CP=20000+30000
             =50000

total SP=19000+32400
             = 51400

therefore, profit=51400-50000
                         =1400

therefore, profit%=(1400/50000)*100
                            =2.8% gain.....

Answer 2

Video=>

CP=20000

loss=5*20000/100

       = 1000

SP=20000-1000

     =19000

TV=>

CP=30000

loss=8*30000/100

       = 2400

SP=30000+2400

     =32400

therefore,

total CP=20000+30000

             =50000

total SP=19000+32400

             = 51400

therefore, profit=51400-50000

                         =1400

therefore, profit%=(1400/50000)*100

                            =2.8% gain.
