Answer: C I got E for this question. Followed the below approach. What if we consider m=14 and n=28 => Not an integer If m=28, n=28 => integer. What did i do wrong?

Hi Bunuel, Please confirm if the below is correct... If it was given : m is not necessarily an integer then the answer would be E ? My reasoning: 1) m could 14 x integer or m could be 14 x 2.5
2 ) n = 2 or 7
Then by combining 1 and 2, m/n can still be fraction ( 2.5 in this case) hence E

I'm quite sure that 2.5 x 14 is no valid multiple of 14

I got this question wrong since I didn't think "Divisor" can refer to a "Factor". From what I knew, a number divided by a divisor, may/may not yield a remainder. Doesn't say anything about the divisor being a factor. Turns out a divisor and factor are the same

Statement 1: m = 14k, where k is a positive integer. Can't say if m/n is an integer since 14/3 is not an integer and 14/7 is an integer.
Statement 2: n is a divisor of 14. This means n can be 1, 2, 7 or 14. But the statement alone does not tell us about m/n. m/n could be 5/7 (is not an integer) or 14/7 (is an integer).
Statements 1+2:
m = 14k and n=1,2,7 or 14. For all the 4 values of n, m/n is an integer. Hence this is sufficient to answer weather m/n is an integer. Hence answer is C

The attempted questions should also show the answer test taker opted for initially when clicked on explanation. After a long test you don't remember what option you chose and it can help you assess your own mindset while making a particular mistake. But this should only be shown when clicked on explanation. otherwise, it needs to be hidden.

I think this is a highquality question and I agree with explanation.

Answer: C Please help me clear my confusion: When statement 2 says that "'n' is a divisor of 14", why did we assume that it is a factor of 14 ? since it is a divisor, it can or can not completely divide 14 or any of its multiples. Any help would be appreciated. Thanks in Advance!!
