A shopkeeper sells two T.V. sets at the same price. There is a gain of 20% on one TV. and loss of 20% on the other. State which of the following statements is correct
Let the S.P. of both the T.V sets be Rs. x.
Then, C.P. of the T.V set at a gain of 20% = Rs. 100×x120= Rs. 5x6
C.P. of the T.V set at a loss of 20% = Rs. 100×x80= Rs. 5x4
Total C.P. = Rs. (5x6+5x4)= Rs. 10x+15x12= Rs. 25x12
Total S.P. = Rs. 2x
Loss = Rs. (25x12−2x)=Rs. x12
Loss % =x1225x12×100=4 %
