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".
"Do so" is the correct usage when "so" refers to an action."Do it" is the correct usage when "it" refers to a noun.
As "do" generally refers to actions, "do so" is more often correct than "do it".
"Confusing-cause-with-effect"
A favorite GMAT CR fallacy.
Example: Every time I dream, I sleep.
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.
