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".
In DS, an answer is achieved only when the answer is "consistent".
Q. Is X a multiple of 24?(1) X is a multiple of 6.(2) X is a multiple of 4.
X = 24 satisfies both (1) and (2), leads to "Yes".X = 12 satisfies both (1) and (2), leads to "No"."Inconsistent". Hence, insufficient. Answer is E.
In DS, beware of "exceptions".
Q. Is X positive?(1) |X| = X.
Because of the exception "X = 0" case, this statement is insufficient.
