Question stem -- blah blah blah
S1) y is a multiple of 100
S2) y is a multiple of 300
I read somewhere you can eliminate answer A without having to even reading the question stem
Q1) could someone elaborate on this DS strategy (why A is wrong in all cases)
Q2) where can I learn more about this strategy
Q3) if anyone can give some other simpler examples of this strategy, so I can internalize this, that would be great !

Hello
jabhatta@umail.iu.edu,
As far as my knowledge goes, you should never even think of eliminating any of the answer options before working on the question stem. You can do it at your own peril.
Also, there is no strategy which says that A is wrong in all cases. Nothing could be further than the truth. There are hundreds of questions where S1 is sufficient to answer the question.
When it comes to referring content related to GMAT Prep, my advice to you would be to exercise some prudence in evaluating the quality of the content and also the source. When you read, I’d request you to read carefully without missing out on essential details. Making notes will only ensure that you retain whatever you have read, to be used when you might need it most.
I make this point specifically because your first few statements gave me an impression that you don’t recall a lot of what you read. It also makes me doubt whether the source was a reliable one.
To help you with general strategies for Data Sufficiency questions, here’s a link to one of our more recent posts on DS strategies. You also have a free download of the Dos and Don’ts on DS questions. I’m sure that this will help you hone your skills of solving DS questions.
