A VCR and TV were bought for Rs 8,000 each. The shop keeper made a loss of 4% on the VCR and profit of 8% on TV. Find the gain or loss percent on the whole transaction.
Given CP of VCR = Rs.8000
loss on VCR = 4% of CP
= (4/100)×8000
= Rs.320
CP of TV = Rs.8000
Profit on TV = 8/100×8000
= Rs. 640
Since, profit amount > loss amount.
So, shopkeeper got profit.
∴ Profit on whole transaction =Rs.(640−320)
= Rs.320
∴ Profit percentage = profit amount /total cost amount×100
=320/(8000+8000)×100
=(320/16000)×100
=2%
