Each column of the table can be sorted in ascending order by clicking on the word "Select" above the table and choosing, from the drop-down menu, the heading of the column on which you want the table to be sorted.

Consider each of the following statements about these sales figures. For each statement, indicated whether the statement is true or false, based on the information provided in the table.

1. True With this question, the author is hoping to draw you into a time pit of calculations but will reward you for efficient logic if you see that the calculations are unnecessary. On a true/false question like this, it's typically best to take the statement and hold it up to scrutiny; in this example, the statement is that "Spray cleaners generated more dollar sales than any other single type of bathroom cleaner". Your burden of proof, then, is to find one type that could have outsold spray cleaners - you only need to consider the cleaner types that are even "contenders". Accordingly, Powder cleaners are irrelevant - there are only two such cleaners and the leading cleaner doesn't have enough separation from the field to make it a runaway category. The decision to be made is between Spray and Aerosol, and so your mission is to determine which sold more. You can effectively do this by viewing it as a "horse race" and not a calculation. Spray starts with two higher-sellers than Aerosol, earning approximately $33M and $27M to Aerosol's two biggest totals, $22M and $21M. This gives Spray a $17M "gap" that Aerosol needs to make up, and with the next highest seller also a Spray Cleaner, the gap widens to nearly $18M. From there, you can simply compare one-to-one the remaining Spray and Aerosol cleaners on the Dollar Sales list to see whether the gap will come down to something competitive. It does not - notice that further down the list the dollar figures become so small that they'll make little if any dent in that gap between Spray totals and Aerosol totals. Rather than calculate, you can logically call this one a runaway just by judging the gaps at the top of the list and noting the limited opportunities for Aerosol to close it down.
   
   
2. False. Of the six cleaners to experience a decrease in average price, only two were aerosol cleaners. To most quickly solve this problem, sort by the "$ change" field to get the reduced-price items aligned together so that you can quickly determine which types of cleaners make up that group of six.
   
   
3. True. This question may appear to require you to perform some calculations, but it can safely be inferred from the data that Ultra Shine had a significantly greater increase in unit sales. Deluxe's Lemon Powder cleaner experienced a substantial (16.7%) loss, and its other two cleaners each had lower percentage unit sales changes than did the top two Ultra Shine cleaners, with the Ultra Shine cleaners each having a higher total volume than the highest Deluxe cleaner. With the third Ultra Shine cleaner also experiencing a percentage increase, it should be relatively clear that the Ultra Shine cleaners had a substantially higher unit sales increase than did the cleaners made by Deluxe.
   
   
4. True. Each of the six Orange sprays experienced a positive % change in unit sales. To most efficiently solve a problem like this, sort by the fragrance type to align all six like fragrances together, then check each for a positive or negative % change in unit sales.
