D Correct answer
Explanation

Let CP = 100. Loss = 30% of 100 = 30. SP = 100 - 30 = 70. Loss on SP = (Loss / SP) * 100 = (30 / 70) * 100 = 300 / 7 = 42.85%. Since this is not listed, the answer is None of these.

AI explanation

Let the cost price be 100, so a 30 percent loss makes the selling price 70. The loss percentage calculated on the selling price is given by (Loss / Selling Price) * 100. This calculates to (30 / 70) * 100 = 300 / 7 = 42 6/7 percent. The correct answer is None of these.
