CLUB-Y

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.

males = m
females = f

Democrats=>
male = m/2
female = 3f/5

(1) In club Y the number of female members is one less than the number of male members.
f = m-1
ratio = m/(m-1)

we dont know the value of m

Insufficient

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

male republicans = m/2
female democrates = 3f/5

m/2 = 3f/5
m/f = 6/5


Sufficient



Option B
