It's a good question! As pointed out in the official MGMAT explanation for this question (in the version I've seen, the answer choices are provided in decimals rather than square root form), estimation is an excellent way to solve this question. Problem Solving statements are always drawn to scale unless otherwise stated, and an estimation will clearly show that x is a little less than 1. Only one answer choice is less 1.

In the figure above, ABCD is a square, and the two diagonal lines divide it into three regions of equal area. If AB = 3, what is the length of w, the perpendicular distance between the two diagonal lines?

a. 3√2 – 2√3 b. 3√2 – √6 c. √2 d. 3√2 / 2 e. 2√3 – √6

Can you solve this in 2 min?

Mgmat version is quite hard if you don't estimate. I found w=3√2 - 2√3, but spent 2 minutes to figure out what is the decimal version. I think this question is basically saying us you can use estimation in PS when you are stuck.
