Not sure shovan85 wrote:Any integer power of 10 when divided by 3 the remainder will be 1. so there will be always a case of fraction. How can we see the options as we have a definite answer before going to options?
Hence IMO D
Oh My God!! I have taken it as 10^(M+N) not (10^M)+N..... LOL thats why it was not making sensegoyalsau wrote:shovan85 wrote:Any integer power of 10 when divided by 3 the remainder will be 1. so there will be always a case of fraction.

Hence IMO D
OA is E
I marked A
Because i think any power of 10 will be like 10, 100, 1000, 10000 ......
now if we add 5 to it even then it will be divisible by 3 like 105, 1005, 10005..
If MN is even than we can't figure out much because it can be even * even or even * odd.
so thought its not enough.
I am not able to understand why answer is not A
U r right!! Be sure u do it from an official source.goyalsau wrote:shovan85 wrote:Any integer power of 10 when divided by 3 the remainder will be 1. so there will be always a case of fraction. How can we see the options as we have a definite answer before going to options?

1.N=5
2.MN is even
I think it is a pretty good question with all its traps. I DO NOT think it should be written with any more or any less sighs, brackets etc....why? Well one should know that 10^m has to be solved before adding ........goyalsau wrote:If M and N are integers,is (10^M+N)/3 an integer?
1.N=5
2.MN is even
Excellent point!narik11 wrote:It has to be option E:
It says just integers may be positive or negative.
Option 1 works fine for positive integers and for the other scenario it doesn't
Option 2 can be eliminated as discussed in the above posts.
i hate it when you guy dont post precise questiongoyalsau wrote:If M and N are integers,is (10^M+N)/3 an integer?

It is neither!diebeatsthegmat wrote:i hate it when you guy dont post precise questiongoyalsau wrote:If M and N are integers,is (10^M+N)/3 an integer?

is it (10^M)+N or 10^(M+N)??????
As shown in posts above the questions is -uwhusky wrote:The issue is that the question was not written correctly.
(10^M)+N and 10^(M+N) are VERY different.
I am not trying to get in an argument here, but was perplexed as to how we (many people) in the group could not understand the question as is.uwhusky wrote:Since GMAT isn't written in symbols, whether this question was written correctly is besides the point. Obviously there's some confusion whether it's 10 ^(M+N) or (10^M) + N, and I guess you knew all along. Whoopee for you!
