c


(1) Condition 1 alone gives us: Still not sufficient to find ratio of males/females
demo rep total
male 21 m
female 53 m-1
total 74

(2) Condition 2 alone give us

demo rep total
male 21 53 m
female 53 f
total 74

Although m=74, no hint for relation to f (Insufficient)

Combining 1+2, we can find ratio of m/f, thus c

Democrats = 74

1) M=F+1 => insuff
2) M-21=53 => M=74 => insuff
1)+2) plugin 74 => M/F=74/73 => suff

My answer is C...

A is insufficient because it only give you a relationship between the total no. of males and females without giving any numbers


B alone is insufficient because it gives you no idea how many female republicans thre would be


A and B together give number of republican males (53) and a relationship between the total number of males and females which enables you to calculate the ratio of males:females

janice, thats a good DS problem. as far as explaning the OA - B, i can say that since Male Reps = Female Dem -> Male Reps = 53;

Male Dems + Male REps = 21+53 = 74 -> ratio of male to female is 74/53 which will only make sense if there are no Female Reps, who are not mentioned anywhere in the stem. does anyone else have an explanation of B??

i do not think that B could be the OA. it should be C.

the first sentence in the stem reads - in club Y all the members are either Dems or REps. then there are the figures for the M/F distribution of Dems. there is no mentioning that there HAVE to be female REps , hence B suggests that it could be theanswer. althought it is not a very convincing one it is a possibility. too bad, so is C. MA i see what you're saying. I think this question needs more info. janice where did you get it from ??

guys you´re gonna kill me! :lol:

I made a mistake in the post,the question should be:

All of the members of club Y are either Democrats or Republicans. If 1/2 of the male members and 3/5 of the female members are Democrats, what is the ratio of the number of males to the number of females in the club?

(1) In club Y the number of female members is one less than the number of male members.
(2) In club Y the number of male Republican members is equal to the number of female Democratic members.

OA is B.Please check out my reasoning and correct me if I´m wrong:

MD:male democrats
FD:female democrats
MR:male republicans
FR:female republicans

MD=M/2
MR=M/2
FD=3/5F
FR=2/5F

MR=FD
M/2=3F/5.From here I got: M=6F/5

Then the ratio is: M/F OR (6F/5)/F=6/5.
