We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
We need to know the sign of \(n\) and its divisibility by 16 to answer the question.
Statement (1) by itself is insufficient. We know that \(n\) is divisible by 4, but we do not know whether \(n\) is positive or negative.
Statement (2) by itself is insufficient. Statement (2), is S1 squared and provides no new information. We know that \(\frac{n^2}{16}\) is a positive integer, but we do not know whether \(n\) is positive or negative.
The key to getting this question right is to read carefully. Note the use of "positive" integer & the implications of its usage in statement (2) and not in statement (1) and how the squares cancel out the use in statement (2).
In general, one could get many questions right just by reading them carefully.
