Q. A man sells an article at a profit of 16⅔%. If he had bought it for 10% less and sold it for ₹30 less, his profit would have been 25%. Find the original cost price.
✅ Correct Answer: (C)
₹400
Explanation: Let CP = x. Original SP = 7x/6. New CP = 0.9x and new SP = 7x/6 - 30. Since new profit is 25%, 7x/6 - 30 = 1.125x. Solving gives x = ₹400.
