Explanation

Quantity A is 20 percent of yesterday’s price of the table. Since yesterday’s price is not given, you cannot calculate this quantity. Similarly, you cannot calculate Quantity B. In the absence of further information with which to compare the two quantities, the correct answer is Choice D.

Yup. Sandy is spot on with the explanation. You need to know the dollar value or at least some relationship between the price of two to come to a conclusion.
