An authorised rice dealer purchases rice at ₹32 per kg and sells it at ₹40 per kg. But while selling, he is giving only 900 grams instead of 1 kg. Find the actual profit percentage of the dealer (Correct to one decimal place).
Answer & explanation
Correct answer: option 4
⇒ Dealer sells 900 grams of rice instead of 1 kg
⇒ Cost price of 900 grams = \(\frac{900}{1000}\) × 32 = 28.8 Rs
⇒ Selling price of 900 grams will be equal to selling price of 1 kg
⇒ Selling price of 900 grams = Rs 40
⇒ Profit = SP – CP = 40 – 28.8 = Rs 11.2
⇒ Profit % = \(\frac{11.2}{28.8}\) × 100
⇒ Profit % = 38.9 %
