Question: 540
18. The product of integers x and y is divisible by 36. If x is divisible by 6, which of the following must be true?
I. y is divisible by x.
II. y is divisible by 6.
III. 
is divisible by 6.
A. None
B. I only
C. II only
D. I and III only
E. II and III only
Correct Answer: A
Explanation:
A Let's try plugging in some numbers for this problem. Start by choosing 18 for x and 2 for y. This makes their product 36, which is divisible by 36. You also made sure to pick a value for x that is divisible by 6. Using these numbers, let's look at statements I, II, and III. Are they true? Statement I is not true, because 2 cannot be evenly divided by 18; because statement I is not true, you can eliminate B and D. Now what about statement II? It's also false, so you can cross off C and E. This means our answer must be A.
