A shopkeeper buys sugar at ₹25 per kg. He marks it at ₹32 per kg and allows a 20% discount on the marked price. While selling, he uses an 800 g weight instead of 1 kg. There is no other loss or expense. What is the overall profit or loss percentage of the shopkeeper?
28% profit
Selling price the customer pays for 1 kg: \(32\times0.80=25.6\).
Actual goods given (800 g) cost the shopkeeper only \(25\times0.8=20\) for that transaction.
Profit: \(25.6-20=5.6\); profit percentage \(=\dfrac{5.6}{20}\times100=28\)%.
Hence, the shopkeeper makes an overall profit of 28%.
