I got C,

1st is not SUFF, says nothing about Y
2nd is not SUFF, says nothing about X

Both combined are SUFF.

the number of people who are in both X and Y clubs is the same.

The number is 20% of X, meanwhile it represents 30% of Y.

0.2X=0.3Y, thus X is always more than Y, works cuz number of members {X&Y} can be represented only by positive intengers, can not be represented by fractions, zeros and negative intengers, in this problem particularly.

stem 2 doesnt say dat .2x=.3y it can be more or less...v cant assume!

v cant get any ans
X can b 100, 200, 500 etc..same is wid Y it can b 10, 50, 1000 etc..
X can be greater than Y or it can b less..so it is E

v cant get any ans cuz d no. of members of X and Y are not known... X can b 100, 200, 500 etc..same is wid Y it can b 10, 50, 1000 etc..

Read the question carefully,

common Gmat trap. =)

okk lemme try again..
st1--insuff
st2-insuff
when v combine... supp x=1000 n Y=1000
st1 says in club X 20% members are of Y - so X has 800 + 200
st2 says in club Y 30% are members of X -so Y has 700+300...
bt it doesnt specify that 30% of X represents exactly d same no. of members as 20% of Y... so it can be either X=Y , x>y or x<y

wot is OA?

if club X has 200 members (as you noted above) who have club membership for club Y (too), than there should be the same number of members for club X in Club Y, in other words if there are people who are members for both clubs than they have equal number (i mean same number of people) of members who are members for both. It is not possible that for club X there 200 two-club members and in club Y there are 300 two-club members.
(still seems confusing???)
