I have a question for this type of DS problem. If one isabsolutely sure that statement 1 is sufficient, during a exam under time pressure, could we plug statement one's given variable into statement 2 to test out?
For example:
Statement 1) Given x=1/2
"I'm sure that it is possible to get y if we have 0 and X=1/2 on the number line. So sufficient."
Statement 2) Given y-x=2/3
"Since I'm confident that statement one is sufficient, let's try plugging in 1/2 for x."
so:
y-x=2/3
y-(1/2)=2/3
