Original weight of rice = 1 kg = 1000 gm
Let cost of 1 gm is Rs. 1
Cost price of 1000 gm = Rs. 1000
Selling price of 850 gm = Rs. 1000 (? giving only 850 gm instead of 1000 gm)
Profit = [error/ (true weight)] × 100
⇒ Profit = [(1000 - 850)/ 850] × 100 = (150/850) × 100 = 17.65%
∴ profit % on 5kg is equal to profit on 1 kg which is 17.65%
Let cost of 1 gm is Rs. 1
Cost price of 1000 gm = Rs. 1000
Selling price of 850 gm = Rs. 1000 (? giving only 850 gm instead of 1000 gm)
Profit = [error/ (true weight)] × 100
⇒ Profit = [(1000 - 850)/ 850] × 100 = (150/850) × 100 = 17.65%
∴ profit % on 5kg is equal to profit on 1 kg which is 17.65%
