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".
Understanding the "intended meaning" is the key to solving SC questions.
Approach for solving SCs:
1. Read the mother sentence.2. For underlined part, move to answer choices.3. Compare vertically to observe the difference in the choices.4. Eliminate 4 choices through vertical comparison while reading horizontally.5. Read the sentence end-to-end before marking an answer choice.
