Question: 623

4. The price of a suit is reduced by half, and then the resulting price is reduced by 10%. The final price is what percent of the original price?

  • A. 5%
  • B. 10%
  • C. 25%
  • D. 40%

Correct Answer: E

Explanation:

When there are percents or fractions without a starting or ending value in the question stem, feel free to Plug In. For instance, Plug In $100 for the starting price of the suit. It is reduced by half, so one-half of $100 is $50, and the new price of the suit is $50. The suit is then reduced by 10%, so 10% of $50 is (50) = (50) = = 5. Subtract this from $50 to find the new price of the suit: 50 - 5 = 45. The final price is $45. The final price is what percent of the original translates to 45 = (100), which makes the math easy! 45 = x, so the correct answer is (E).
