Q. A man purchased two articles for ₹6000. He sold one at a profit of 20% and the other at a loss of 10%. If the total selling price was ₹6600, find the cost price of the article sold at a profit.
✅ Correct Answer: (C)
₹3000
Explanation: Let CP of the article sold at profit = x. Other CP = 6000 - x. 1.2x + 0.9(6000 - x) = 6600. Hence, 0.3x = 1200, so x = ₹4000. Therefore, the correct answer is ₹4000.
