A jeweler marks a necklace at 30% above its cost price. She gives a cash discount of ₹150 on the marked price. If the necklace is sold for ₹1800 and she earns a profit of 20%, what is the cost price of the necklace?
Answer
The correct answer is C: 1500. SP = ₹1800 at 20% profit: CP = 1800/1.2 = ₹1500. Marked price = 1500×1.3 = ₹1950.
