Since PS||QR the shortest distance between the lines PS and QR is the perpendicular between the lines. Whichever segment PQ or SR is closer to becoming a perpendicular is the shorter of the two segments. For this to happen the angles x or y must get maximized towards 90 degrees for their length to become minimum.

Statement 1
x > y
this implies that x is closer to 90 degrees than y. Hence PQ is closer to being perpendicular and thus we can say that PQ is shorter than SR. Sufficient.

Statement 2
x + y > 90
Does not tell us the relation between x and y. Here x could be greater than y (x = 80, y= 70) and satisfy the inequality, or x could be lesser than y (x = 70, y = 80) and still satisfy the inequality. Hence we cannot say which angle is closer to 90 degrees so we cannot determine which line is closer to becoming perpendicular and thus shorter. Not sufficient.

Hi,

remember that the shortest distance between any two points is a straight line. So, the question is basically asking you whether the statements will tell you which line travels more "perpendicularly" from bottom to top (or top to bottom).

These type of DS questions are real time savers.

The minimum distance between a point and a line can be calculated by drawing a perpendicular passing through the given point to the line.

If you decrease the angle the distance increased. Since x>y => PQ< RS

Thus A. B is irrelevant.

What if it was not stated x and y both less than 90?? Then the answer would have been E.

Very nice question.

I don't think so. I'd say it's a 600-700 level question.
I'm not an expert but I didn't find this question difficult, when I don't seem to solve correctly most of the 700-level questions.
