A dishonest dealer professes to sell his goods at the cost price, but he uses a false weight of 850 grams per 1 kg weight.
Formula used:
Percentage gain = \(\left(\dfrac{\text{True Weight} - \text{False Weight}}{\text{False Weight}}\right) ×\) 100
Calculation:
True Weight = 1000 grams
False Weight = 850 grams
⇒ Percentage gain = \(\left(\dfrac{1000 - 850}{850}\right) ×\) 100
⇒ Percentage gain = \(\left(\dfrac{150}{850}\right) ×\) 100
⇒ Percentage gain = 0.1765 × 100
⇒ Percentage gain = 17.65%
∴ The correct answer is option (1).
