Hi there, if we can prove that the final score was a simple average then we can answer NO to the first part. A quick calculation reveals that the simple average for Susan is (10+20+35)/3 = 21.67 hmm so looks like its some sort of weighted average. Ok, lets sort by Final score and let your eyes roll down the list. For all the trainers you will notice that the final score is skewed towards the Client 1 and 2 data points. At this point I can intuitively say that either Client 1 or 2 data points have a greater weight. So the answer is NO, Client 3 does not have the same weighting than client 2.

Atleast this is how I would approach the problem and choose the answer. What is the OA/OE?

Point of clarification: The use of the word "weight" really intends to be "weighting" as in saying that the weight loss of two clients have "equal weighting" in terms of the final score calculation.

The wording may be clearer here:

"In calculating the final score for the contest, the weight loss for a fitness trainer's third client (Client 3) had equal weighting as the weight loss on Client 2."

In other words, did the weight loss in client 3 have the same level of input/impact on the final score calculation as did the weight loss for client 2?

But does this clarification change macjas's explanation?
I still think the answer would be 'No'. However, it would be helpful to know the explanation behind 'yes' from the Gmat Pill
Thanks in advance

Try assuming that statement (1) is true. Now test that assumption and see if you can challenge the assumption and make it wrong. If you can make it wrong, then you know the answer is NO. If everything adds up for all the trainers using your assumption that the 2nd column and 3rd column carry equal waiting, then you know the answer is YES.

Think - system of equations. We've also made the video explanation free for guests so you can click "show answer" and see the video explanation.
