Question

VCR and TV were bought for rupees 8000 each the shopkeeper made a loss of 4% on VCR and a profit of 8% on TV find the gain or loss percent on whole transaction.​

Answer 1

Answer:

the gain in the whole transaction = 2%.

Step-by-step explanation:

Given:

Cost price(CP) of each article=Rs. 8000

Profit of 8% on TV

Loss of 4% on VCR

Cost price of TV =Rs. 8000

Profit on  TV = Cost price × profit %

Profit on TV =8% of 8000

= $8000$ × $\frac{8}{100}$

$= 80$ × $8$

= Rs. 640

Cost Price of VCR =Rs. 8000  

Loss on VCR = Cost price × Loss %

Loss on VCR=4% of 8000

$= 8000$ × $\frac{4}{100}$

$=80$ × $4$

= Rs. 320

Since profit  is more than loss,

Hence, the shopkeeper gains net profit

Net Profit=640−320=Rs. 320

Now

Total cost Price of both article=8000+8000=Rs. 16000

Profit(%) =  $\frac{profit}{C.P.}$ × $100$

Profit (%) =  $\frac{320}{16000}$ × $100$

Profit(%) =  $\frac{32}{16}$

Profit(%) = 2%

Hence, the gain in the whole transaction = 2%.
