I have gone thru various posts on this forum on how to nail down the Inequality questions in DS. Tried various ways. But nothing is working out for me to pick the correct ans with confidence. Finally I decided to go with the graphical approach. have to spend some time on understanding the concept behind it. And atleast I think I CAN solve them with confidence. I have documented couple of points that I gathered by googling the net / by searching the forums.

Hope for some of you, who wanted to solve the Inequality questions in a graphical way, MIGHT find it useful. :)

Couple of errors/exceptions:
=====================

Quote:
Section 7:
==========
3. Now if the shaded region identified in step 2 covers the entire shaded region identified in step1
then the Statement clue alone is sufficient.
Show more

I believe that the better way to evaluate this is to make sure that the entire solution space covered by each statement
falls under the question stem condition. Example is walkers post. Note that the statement (1) is a subset of the question
stem but all cases of statement 1 is a subset of the question which means SUFFICIENT.

Quote:
Section 3
If the slope of the line is positive, then slope of the line is positive (line will be running from bottom right to top left).
Show more

Above is an error, line will go from bottom left to top right if slope is positive?

I have corrected the point mentioned in the Section 3. I reloaded the document.

Now coming to the point under section 7, I think I didn't get what you were trying to say.

But my understanding is that if the region identified in each statement should be the super set of the question stem, then the statment clue is sufficient. Else the statement is not sufficient.

ConkergMat,

For the section 7, that you mentioned, I think I understood my misinterpretation. I have corrected myself and also the document. Thank you for pointing my mistake.

For those who might have downloaded the document, please use the latest one. I have uploaded the corrected one.
