A dishonest shopkeeper sold onions at Rs. 30/kg which he has bought at Rs. 20/kg. He gave 750g instead of 1 kg. Find his actual profit percentage.
1). 10%
2). 25%
3). 50%
4). 100%
Weight of onions bought by customer = 1 kg
Actual weight of onions received by customer = 750 g = 0.75 kg
Price paid by the customer = Rs. 30
Actual price of 0.75 kg = 0.75 × 20 = Rs. 15
∴ Money earned by the shopkeeper = 30 – 15 = Rs. 15
∴ Profit percentage = (15/15) × 100 = 100%
