CorrectNot quiteAnswer A

Correct answer: A

Explanation

  1. Price paid = 0.8×0.9=0.720.8 \times 0.9 = 0.72 of the marked price.

  2. Single equivalent discount = 100%−72%=28%100\% - 72\% = 28\%.

Worth noting

The 10% is taken off the already-reduced price, so the discounts do not add to 30%. 72% is the price paid, not the discount.
