If you chose 111,060 you were SO close to the correct answer but made a small mistake-you didn't change the aggregation to AVERAGE! This is one of the common mistakes many test takers make, so keep this in mind.

To reach the correct answer, follow the steps below:

1) Draw Assortment to the Column shelf, and drag Year to the Rows Shelf. Then Drill down further on Year to accomodate Quarters and Months as well! Although this seems enough, DON'T FORGET to change the aggregation like in the

next step, which will completely change the values!

All other options are ways recommended to make your text more readable!

Correct Answer: C

2) Now, click on the Profit pill in the Rows shelf, go to quick table calculation and choose Percent difference:

3) Finally, click on the Show mark Labels icon:
