**Question 1 –“What is the average…” **

OG Explanation is fine.

**Question 2 – “What is the value…”**

OG Explanation is fine.

**Question 3 – “If n is an integer…”**

OG Explanation is fine. “then n is divisible by how many positive integers” is the same as “how many factors does n have”

Statement 1: As per the OG explanation, there can only be 4 factors: 1 p, q, pq. SUFFICIENT

Statement 2: 2^{3} has 4 factors: 1, 2, 4, and 8. Integer n has the same number of factors. SUFFICIENT

The correct answer is D: Each Statement Alone is Sufficient.

**Question 4 – “If l and w represent the…”**

OG Explanation is decent.

**Question 5 – “A retailer purchased….”**

OG Explanation is too short.

Statement 1: We know nothing about y. INSUFFICIENT

Statement 2: We don’t know anything about the dollar value. Nor do we know the value of x and y. If x=50, y=45 or x=10 and y=5. INSUFFICIENT

Combining both statements, x=15 and y=10. We still don’t know anything about the price. The list price could be $100 (in which case the TV was bought for $85 and sold for $90) or the list price could be $200 (bought for $170 and sold for $180) or any other number for that matter.

The correct answer is E: Both statements together are still not sufficient.
