Kudos for the right answer and explanation[/m]

D  

A percent question with no specific values indicates a Hidden Plug In question. The question mentions “the original price,” but gives no actual number, so assume that the original price of the garment was $100. After the first reduction, the sale price was $100 – (20% of $100) = $80. After the second reduction, the final price was $80 – (10% of $80) = $72. The total reduction from the original price was therefore $28, which is 28% of the original price. Choice (D) is the answer.
