Question

A VCR and TV were bought for 78.000 each. The shopkeeper made

loss of 4% on the VCR and a profit of 8% on the TV. Find the gain or loss
percent on the whole transaction.​

Answer 1

Profit % is 1.94% .

Explanation:

The CP of both VCR and TV were same that is Rs 78,000 . So ,

`=> CP \ of \ the \ buyer \ = \ Rs78,000 * 2 = Rs 156,000`

As per Question , on one he made a loss of 4% and profit of 8% on the other .

And , the net SP would be ,

`=> Total \ SP \ = \ (96)/(100)* Rs 78,000 + (108)/(100)* Rs 78,000 \\\\=> Total\ SP = Rs 74,800 + Rs 84240 \\\\\boxed{\red{\bf => Total \ SP= Rs 159,040 }}`

So , here clearly SP > CP . So , there's a profit .Hence profit % would be :-

`=> Profit \% = ( SP - CP )/(CP)* 100 \\\\=> Profit \% = (Rs 159,040-Rs156,000)/(Rs156,000)* 100 \\\\=> Profit\% = (3040)/(156000)* 100 \\\\\underline{\blue{\bf => Profit\% = 1.94 \% }}`
