5 A VCR and TV were bought for Rs 8,000 each. The shopkeeper made a loss of 4% on the VCR and a profit of 8% on the TV. Find the gain or loss percent on the whole transaction.
The cost price of the VCR = Rs. 8000
The cost price of TV = Rs. 8000
Now, He made a loss of 4% on VCR.
Selling price (SP) of the VCR = (100-4)% of CP = 96% x Rs. 8000 = Rs. 7680
Again, He made a profit of 8% on TV.
Selling price (SP) of the TV = (100+8)% of CP = 108% x Rs. 8000 = Rs. 8640
Net Selling price = Rs. (7680 + 8640) = Rs. 16320
Net Cost price = Rs. (2x8000) = Rs. 16000
Since, SP > CP, he made a net profit (gain)
Now, Net Gain = CP - SP = Rs. (16320-16000) = Rs. 320
Gain % = = 2%
The shopkeeper made a gain of 2% on the whole transaction.
