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. Find the percentage of his gain. (Correct up to two decimal places)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 17.65%.
Let the cost price of 1 kg goods be ₹100
So, The cost price of 850 grams = 100 × 850/1000 = ₹85
Now,
Profit = Selling Price - Cost Price
⇒ 100 - 85 = ₹15
Gain% = Profit/Cost Price × 100
Gain% = 15/85 × 100 = 17.65%
Thus, The dishonest dealer's percentage gain is 17.65%
