In DS, beware of "exceptions".
Q. Is X positive?(1) |X| = X.
Because of the exception "X = 0" case, this statement is insufficient.
In DS, when you are able to solve "too easily", you are probably missing a trap.
Q. Which integer is the highest common factor of four positive integers A, B, C, and D?(1) A= 27, B=49.
Unlike what many students will think, this statement is "Sufficient". Because no matter what "C" and "D" are, if HCF of "A" and "B" is 1, the answer is going to be "1".
The mind-map-strategy for RCs
1.Skim through the first paragraph.Take your eyes off the screen.
2. Ask yourself the paragraph's "purpose" .Purpose is always very, very brief.Avoid paraphrasing the details.
3. Skim through the next paragraph.Take your eyes off.Ask yourself the paragraph's "purpose".Link the purpose of the first paragraph with that of the second.
4. Keep repeating Step 3 for all the subsequent paragraphs.
