A dealer professes to sell goods at a loss of 10% but uses a weight of 750 g instead of 1 kg. What is his real gain or loss percentage?
Show answer & explanation
Correct answer: B
Explanation
Given:
Claimed Loss = 10%
Actual Weight = 750 g (instead of 1 kg)
According to the formula:
Loss of 10% ⇒ Selling Price = 90% of Cost Price
Assume the Cost Price of 1 kg = ₹100
Selling Price (for 1 kg) = 90% × 100 = ₹90
However, the weight supplied = 750 g
Cost Price of 750 g = 100 × 750/1000 = ₹75
Profit = 90 − 75 = ₹15
Profit % = (15 / 75) × 100 = 20%
