Let cost price of TV & DVD are x,y respectively
TV-loss 5% and DVD-gain 10%; so => (95/100)x+(110/100)y=x+y..............{1}
TV-gain 20% and DVD-loss 10%; so => (120/100)x+(90/100)y=x=y=3000........{2}
the above equation written basis on selling price formula for gain and loss.
ok,now solve these two then we will get x= Rs20,000;which is cost price of TV
