The OA is E.

The following is the explanation:-
Here's a stellar example of the subject-verb sucker punch. Many students are
inclined to pick (A) because "adults carry" makes sense to the ear. But the
subject of this latter thought is "one", which needs to be paired up with the
verb "carries". Use the two/three split and cross off (A) and (B). The rest comes
down to the proper use of the statistics cited in the sentence. (C) and (D) are
incorrect because they use "every" and "each", which suggest that if you take
fifty people off the street and put them in a room, exactly one will be carrying
a handgun. But the point of the sentence is to establish a more general ratio: for
every forty-nine people who don't pack heat, there is one person who does.

I'll go with C

a) one out of every fifty adults carry - 'Carry' is not correct with 'one'
b) every one out of fifty adults carry - nonsensical/changes the meaning
c) out of every fifty adults, one carries - Correct
d) each adult among fifty carries - unidiomatic/changes the meaning
e) one adult in fifty carries - unidiomatic

C. One eagrees with carries.
It makes the second part of the sentence after the comma complete with subject and verb) One carries...

I think its E.
somehow usage of Each/Every is wrong and misleading...

Why is 'fifty' wrong or not clear?
I still feel its E.

Subhash can you please post the OA and OE..
Please post the source as well..

I think the more common usage is to say ‘one out of fifty’; ‘one out of every fifty’ is just to make things a little stretched. ‘One in fifty’ also isn’t much heard of but there seems to be nothing wrong about it. The best option would have been ‘one out of fifty adults carries’
But c) ‘out of every fifty adults, one carries’ can be dispensed with due to its wordiness vis-à-vis choice E
_________________

it should be E...awesome explanation by Subhash...

can we have some more discussion on it . I think its A because there is not only one "one" ...but for every fifty there is one so i think it should be plural?

"every" and "each" used in C and D change the intent meaning of sentence. Correct one is E.
_________________

"one adult in fifty carries" a gun seems to imply something else. But still seems like the best fit considering that C is so wordy.

+ 1 for E.
Every and each are redundant in the rest of the options.

confused between C and E.....i think E changes the meaning of the sentence....can anyone please explain which is correct between the two options??????

+1 E as C is bit awkward and E is written concisely

Even E is ambiguous because it says one adult in fifty that can also convey that one of age 50 yrs or so...
IMHO C is better than E.

I understand that this Q is bit out of track from GMAC Q but in my opinion out of all the options E is the best choice and in my opinion "one adult in fifty carries" means "one adult among fifty adults" then it makes sense...

Bringing this Question up again, I too am confused between C and E.
I chose C because the Question itself also contains every. Whatever "every" is used to emphasize in given question, that changes if we remove every from the Ans, ie E.
Thus I think E is changing the meaning. However, every in C is correct.

Any suggestions?

Can somebody explain if it would had been" Eight out of every ten" instead of one out of fifty would we still be using carries or carry would be correct option.
I hope i am able to explain my doubt.

For those in doubt: The idiom is :

One X in every 50 (X's)

It is a very common idiom in the western world
