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

Zielflug [23.3K]

Answer:

Profit % is 1.94% .

Step-by-step explanation:

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

$=> CP \ of \ the \ buyer \ = \ Rs78,000 \times 2 = Rs 156,000$

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

And , the net SP would be ,

$=> Total \ SP \ = \ \dfrac{96}{100}\times Rs 78,000 + \dfrac{108}{100}\times Rs 78,000 \\\\=> Total\ SP = Rs 74,800 + Rs 84240 \\\\\boxed{\red{\bf => Total \ SP= Rs 159,040 }}$

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

$=> Profit \% = \dfrac{ SP - CP }{CP}\times 100 \\\\=> Profit \% = \dfrac{Rs 159,040-Rs156,000}{Rs156,000}\times 100 \\\\=> Profit\% = \dfrac{3040}{156000}\times 100 \\\\\underline{\blue{\bf => Profit\% = 1.94 \% }}$
