A dishonest shopkeeper sells article at cost price but he uses a false weight of 900 grams in place of 1kg. Find the profit percentage during this transaction.
Answer & explanation
Correct answer: option 1
Let the price of 1000 gm = 100
Cost price of 900 gm = Rs. 90
Selling price of 900 gm = 100
Profit % = \(\frac{100-90}{90}\) × 100 = 11.11%
