Please post explanation!

Official Explanation

1. False. Super Clean's Fresh Spray had the highest unit sales, but Deluxe's Orange Spray had the highest dollar price increase. On a problem such as this, in which the question asks whether the leader in one category is also the leader in another, it is best to start by sorting by one of the categories. Then, either scan the other column for a higher value, or sort by the second category to see whether the same item stays at the top of the list (when doing that, however, be careful for a "tie").

2. True. Of the six Orange sprays, all experienced unit sales increases. One can best solve for this by sorting by the Fragrance category to align all the Orange items together, then by scanning those together along the "% change" column to see whether any of those products experienced negative or neutral unit sales.

3. False. Four fragrances experienced dollar sales growth but also a decline in unit sales. In a case like this, when the statement says "no fragrance..." you need only find one exception to that universal statement to consider the statement false.

4. True. Super Clean's Fresh Aerosol is the highest-priced item at $4.33, and this price reflects a $0.05 decrease from 2009, signifying that it was the highest-priced item in 2009 as well. Note here that the "current price" column reflects the 2010 price, and that the $ change column shows the difference from 2009. Accordingly, to determine 2009 price, one needs to add the decreases to the 2010 prices or subtract the increases to the 2010 prices; this counterintuitive logic is likely to confuse examinees, making this a tricky question.

Hope it helps
