First GMAT prep from mba website, question #17:

In n and m are positive integers, what is the remainder when 3^(4n+2) is divided by 10.

1) n=2
2) m=1

.... Im so confused in terms of where m fits in this whole question...and why the answer is B: statement 2 ALONE is sufficient.

I'd appreciate any feedback.
Thanks!

Are you sure of the question put up here !!

Is it not 3^(4n+m)/10 or 3^(4m+2)/10 in stead of 3^(4n+2)/10 ?

I'm positive. I copied the question exactly as is from the software downloaded from mba.com - it's the first practice test :?

Should be A right because
3^8 = 81*81 and therefore the remainder is 1...

Just making sure.

Yes, if this question is truly written correctly, the answer would be A.

However, your math is slightly off. If we use n=2 from statement 1, then we would have 3^((4*2) + 2) = 3^10.

Since that is one and only one number, which we could solve for if we wanted, this is enough information to figure out the remainder. Thus, statement 1 is sufficient.

Looking at statement 2, it only tells us something about a totally irrelevant variable m and it is not sufficient.

Since 1 is sufficient and 2 is not, the answer is A.
