A shopkeeper marks price of his articles 12% above the cost price and then allows 12% discount on the marked price. What is his loss percent?

Let CP = 100. Marked Price = 100 + 12% = 112. Selling Price = 112 - 12% of 112 = 112 - 13.44 = 98.56. Loss = 100 - 98.56 = 1.44. Loss percent = 1.44%. Option A (0%) would be true only if the markup and discount percentages were equal, but the base changes after markup. Option B (1%) is close but not exact. Option D (2.4%) would result from incorrectly subtracting percentages directly.
