when n = 6, the answer is yes, but when n = -24, the answer would be no as 0 is not an integer.

Please advise.

(1) - if n is 3, n/6 is not an integer, but if n is 6, n/6 is an integer, so insufficient. (2) - n divided by 6 has a remainder of 0,meaning n has to be a multiple of 6 (0, 6, 12, etc).

I would think the answer is B - (2) alone is sufficient.

It seems that there is confusion on the internet concerning 0 as an integer - my opinion for the GMAT is that 0 should be treated as an integer... does GMAC state otherwise?

0 is an integer, moreover 0 is an even integer. Maybe you have mistaken this property for another: zero is neither positive nor negative?

1. n is a multiple of 3 2. n divided by 6 has a remainder of 0

Though the problem looks pretty straight forward, it underlines a very imp fact regarding Data Sufficiency YES/NO questions and this fact I want to be cleared!

Now, if we look at the individual statements, obviously we choose values and evaluate the Question Stem.

1. n is a multiple of 3

we can select n to be 3, in which the answer is NO and we can select n as 6 in which the answer is YES.

Since data sufficiency basically tests how the sufficiency of data is interpreted, my question is this...

Statement clearly gives us the answer as either YES or NO..and therefore we can answer the question stem as:

4+n/6 is an integer if n=6,12..and it is not an integer if n=3,5 etc

Moving on statement 2, which is sufficient to answer the question stem.

But, the answer is B and I feel it should be D since we can answer the question stem using each statement- either statement is sufficient by itself to determine YES/NO for an "IS" question.

Can someone please clarify my reasoning and advise where I am wrong?

Thanks Rajeev

The point is that in a Yes/No Data Sufficiency questions, statement(s) is sufficient if the answer is “always yes” or “always no” while a statement(s) is insufficient if the answer is "sometimes yes" and "sometimes no".

When a DS question asks about the value of some variable, then the statement(s) is sufficient ONLY if you can get the single numerical value of this variable.

when n = 6, the answer is yes, but when n = -24, the answer would be no as 0 is not an integer.

Can someone clarify whether this question is asking 4 + n/ 6 as a whole or 4 + (n/6)?

4 + n/6 can only mean 4 + (n/6), nothing else. If it were (4 + n)/6 it would have been written this way.

Target question:Is 4 + n/6 an integer?

This is a good candidate for rephrasing the target question (see video below).

If 4 is an integer, then 4 + n/6 will be an integer if and only if n/6 is an integer. Moreover, n/6 will be an integer if and only if n is divisible by 6. So, we can REPHRASE the target question as....

REPHRASED target question:Is n divisible by 6?

Statement 1: n is a multiple of 3 There are several values of n that satisfy this condition. Here are two values that yield conflicting answers to the REPHRASED target question : Case a: n = 3, in which case n is NOT divisible by 6 Case b: n = 6, in which case n IS divisible by 6 Since we cannot answer the REPHRASED target question with certainty, statement 1 is NOT SUFFICIENT

Statement 2: n divided by 6 has a remainder of 0 If n is divided 6 leaves remainder 0, then n is definitely divisible by 6. Since we can answer the REPHRASED target question with certainty, statement 2 is SUFFICIENT
