data sufficiency question
In the figure above, if x & y are each less than 90 and PS // QR, is the length of segment PQ less than the length of segment SR?
Please explain step by step and some rules I should know.
Question : Is PQ < SR ?nickhar130 wrote:sorry also below
1) x > y
2) x + y > 90
Given in the QuestionThouraya wrote:Can someone please explain the rationale behind this problem? I didn't really understand the relation between the length of PS & QR and the measure of the angles...Thanks!
Sometimes it helps to think of real world scenarios to help you visualize what's going on in a question.
Your mistake is a simple one - you didn't take into account the condition set in the question stem:bubbliiiiiiii wrote:Option 1: x>y.
if x =60; y=30, PQ < SR
if x =170 y =30 PQ > SR INSUFFICIENT.
Options 2: x+y > 90
if x = 11; y=80, PQ > RS
if x = 80; y=11, PQ < RS INSUFFICIENT.
Option 1 and 2, together: i.e., x>y and x+y>90
if x = 80; y=11, PQ < RS
if x = 170; y=30 , PQ > RS INSUFFICIENT.
Stuart, Could you please correct my approach and guide me where am I wrong? As per the approach given above I am getting E.
