Hi Carcass...after spending some time and couldn't get any proper relationship among the equations that I made. Finally chose D and that is correct.

But can you share us the solution.

I wasted 4 minutes on this to guess it as D. Can someone please explain how to determine this quicker for test day?

I strongly suggest you read my article here https://greprepclub.com/forum/all-you-n ... -8898.html

Moreover, I guess you have approached the question from a math standing point and not with a profound evaluation upfront: critically.

This is a question in which GRE really goes down to the business. Hitting you hard.

First of all, the first clue you should have about this question is that it misses of a fundamental wording: "the picture drawn the scale". Which means the shape and the form of it is misleading.

Next step, we do know that the sides Ab and DC are parallel and the measure is 7. All EF is 22, which means that ED + CF = 15 (22 - DC >>> 22-7).

Now, the figure can be the following scenarios

Image

The length of Ed and CF could be any combination numbers that add up to 15. Moreover, you do not know the height AD and BC: more flat or higher. See the figures above.

The answer is D without even scratch my paper and sharp once again my pencil because consumed in the process

Hope this helps.
