If you add up the 6 decimals that appear in those 6 circles, you end up with the number 1. The number 1 is the equivalent of 100% of Techtyx's sales, which makes sense since the prompt tells us that Techtyx sells products in 6 regions. There's NO mention of any other company (much less 5 other companies), so it's not clear how you came up with that interpretation. The number 6 refers to 6 REGIONS in which Techtyx sells products.

When I first read it, I understood it as, let's say we have 5 different Appliance Companies (including Techtyx) selling appliances in A region and the total amount of customer transactions they do in such region sums up to 100,000$, so the amount of Techtyx customer transactions in that region will equal to 0.29 * 100,000$= 29,000$.

I know that if understanding it in such way, we can not find out the answer, but how can I understand the intended meaning exactly in the first place I mean, is it because this expression actually could be interpreted in such two ways, or because I am wrong here? And if so, what the definition will be to express the meaning above?

Hi canbtg,

The second question requires you to make some reasonable estimates and calculate the approximate AVERAGE transaction for a region. We're interested in finding the GREATEST average.

The answer choices narrow it down to 4 options: A, C, E and F

First, we have to determine some things about the 4 regions. The center of each circle lines up with a point on the X-axis that determines TOTAL SALES for that region. The number inside the circle represents the percent of total transactions. Here's what we know about the 4 regions:

Region A: about 500K in sales, 29% of the overall transactions.
Region C: about 800K in sales, 33% of the overall transactions.
Region E: about 700K in sales, 5% of the overall transactions.
Region F: about 900K in sales, 15% of the overall transactions.

To make this easy, let's say there were 100 total transactions. Since we're asked for the AVERAGE transaction, we'll need to use the Average Formula. This meansâ€¦.

Region A: 500K/29 ---> Less than 20K per
Region C: 800K/33 ---> Less than 30K per
Region E: 700K/5 ----> About 140K per
Region F: 900K/15 ---> About 60K per

The region with the highest average transaction is E
