Loss= 20000×5÷100= 1000
gain= 30000×8÷100= 2400
total is gain.
total gain= gain-los= 2400-1000= 1400

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.....
