Data Sufficiency

191)
Of 4800 voters who voted for Resolution K, 1800 were Democrat and 3000 were Republican. What was the total number of female voters who voted for Resolution K?
a. ¾ of Democrats & 2/3 of Republicans voted for Resolution K
b. 1/3 of Democrats who voted for Resolution K and ½ of Republicans who voted for Resolution K were female


OA is C


How??

Total Voters = 4800
No. of Democrats = 1800
No. of Republicans = 3000

Qn: Total no. of female voters who voted for Resolution K?

What info is missing? (1) No. of voters who voted for K, (2) Male:Female ratio in no. of voters.

A. 3/4 of Democrats & 2/3 of Republicans voted for Resolution K

We have the total number of voters but we don't know the male-female ratio. Insufficient.

B. 1/3 of Democrats who voted for Resolution K and 1/2 of Republicans who voted for Resolution K were female

We are given only for female. But we can find out for male with the given info.
We have the male-female ratio now but we don't know the total number of voters. Insufficient.

Combined, we have the sufficient information [(1) and (2)] to answer the question. Sufficient.
Hence, C

But as per the question mentioned here it will be B. There is alanguage construct missing here.... the question reads here : Of 4800 voters who voted for Resolution K if the question read Of the 4,800 voters who voted for or against Resolution K then the answer will be C.


Total Voters who voted for the resolution = 4800
No. of Democrats who voted for the resolution = 1800
No. of Republicans who voted for the resolution = 3000

Qn: Total no. of female voters who voted for Resolution K?

A. 3/4 of Democrats & 2/3 of Republicans voted for Resolution K this Insufficient true.


B. 1/3 of Democrats who voted for Resolution K and 1/2 of Republicans who voted for Resolution K were female

Democrats who Voted = 1800; Republicans who voted = 3000.
1/3 are females of 1800 and 1/2 are females of 3000. Why do we need to know the total number of voters. We just need to know the number of female who voted not the total number of females. thus B sufficient.

If we use the 4800 who voted for or against then we would need the number of people who vote for the resolution which can be inferred from 1 and hence the answer C.

Either the original question (or else the OA) has been mistranscribed. The answer to the question posted is clearly B.

This:

There is alanguage construct missing here.... the question reads here : Of 4800 voters who voted for Resolution K if the question read Of the 4,800 voters who voted for or against Resolution K then the answer will be C.

is correct; if the question had read like that, then the answer would be C.

Thanks

Answer can't be B, its C

Because the question stem states "Of the 4,800 voters who voted for or against Resolution K", that's FOR & AGAINST.

Before you post, you should read the posts above. And BTW, it would have to be "for OR against" not "for & against".

I too go for B. Because I got total female voters equals 2100. Why not B?

Hi peddisetty,

You should read my first post above. In general, you should read all the posts in a thread before you post--the answer to your query/confusion may already have been discussed!

Read the question very carefully> then decide.
IN Statement-1: there is no information about female but only for who have voted for Resolution K
IN statement-2 there is information about how many women voted for Resolution-k.

combine them & GO for C

Hey there!

Please look at the posts above yours. There already has been a long debate on the solution and it's conclusive that the answer must be B with the given wordings in the question. OA given as C is incorrect.

I will clarify for all.

The wording in the original question posted by mmslf is incorrect. I have the exact same wording in a gmapt prep doc that has been circulating this site.

However, I received this question while taking the actual gmat prep test and it contains additional info about the male/female split in the question stem.

So, in sum, the answer to the question posed originally by mmslf is clearly B. However, the answer to the correct question in gmat prep is C.

I came across this question in the OG 10th.
Just so there is nt any confusion, i'll paste the question with exact wordings as they appear in the OG :
Of the 4800 voters who voted for or against Resolution K , 1,800 were Democrats and 3,000 were Republicans. what was the total number of female voters who voted for Resolution K ?

1) 3/4 of the Democrats and 2/3 of the republicans voted for resolution K

2) 1/3 of the Democrats who voted for Resolution K and 1/2 of the Republicans voted for Resolution K were females.

each statement alone is definitely not sufficient. But my confusion is that i thought the question does not tell us the total number of democrats or republicans. It just tells us the number of democrats and republicans *who voted*. If there were some people who didnt vote, then how can we say that by combining two statements we can get the answer.

1/3*3/4 of Total democrats + 1/2*2/3 of Total republicans is what we need. 1/3*3/4 of democrats who voted + 1/2*2/3 of republicans who voted is what the entire given data can give us. I don't know what i might be getting wrong, but the question most certainly doesnt tell us that all democrats and republicans voted. Please help.
