Step 1: Identify the conclusion.Step 2: Link the bold part(s) with the conclusion.Step 3: Know what to expect from the correct answer choice.Step 4: Eliminate four choices.
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.
“And” is the only conjunction that can join two singular nouns and make them plural.

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".
Compound Interest= P[(1+r/100)^n –1]
P: Principle invested.r: Rate of Compound interest.n: Period.
"model...after" is a correct, idiomatic usage
