Every Tuesday, we’ll be posting up a free practice question from our database:

Submit an answer and an explanation in the comments by 1PM Pacific Daylight Time on Wednesday, and we will randomly pick a reader who answered correctly (whether by commenting here, tweeting us, or commenting on the Facebook post) to win a free premium subscription to the Magoosh GRE product!

Try it out to see if you can figure out the answer and let us know if you need any hints! The answers will be posted on Wednesdays at 2PM with step-by-step explanations.

The questions will be drawn from various question types and topics, so this will be a good way to get some extra practice on a weekly basis and feedback when it comes to strategies and methods!

Here’s the first question:

Note: Figure not drawn to scale

magoosh is really helpful for me in preparing the new gre,especially in verbal section.feels lucky to found it..:)thanks magoosh.

I’m glad you find the posts helpful, I’ll pass along the thanks to the other authors! 🙂

Area of square ABCD = 25 so side = 5

Side of small shaded square = x

Side of large shaded square = 5-x

(5-x)^2 / x^2 = 9

5-x/x = 3

5-x = 3x

4x=5

x=5/4

The answer is B) 5/4
