Hi...
total members are 100..
(1) The median age of the members in the club C is 30.5 years old.
Possible that it would look to few that this is not sufficient. BUT always work a bit on the sentence
Median age as 30.5 means that it is average of 50 and 51 person..
BUT 30.5 is also the MIDDLE of the age. so what does it tell us ...
It tells us that half are above 50 and half below 50..
so 26+x+4+6=50........36+x=50....x=14
suff
Ofcourse you can find y also 27+y+6 = 50....y=17
(2) y = 17
straight suff...
as two variables x and y..
y is known we can find x
suff

That is one of the strangest tables I've ever seen: the "number of children" who are 33 years old is 26?
Anyway, assuming all 100 "children" are listed in the table somewhere (something the question needs to say), if the median is halfway between 30 and 31, then exactly half, or fifty, of the "children" are 31 or older, and half are 30 or younger. So 26+x+4 = 50, and we can find x. So Statement 1 is sufficient. Statement 2 is clearly sufficient, since then we have every number in the righthand column besides x, and we know those numbers sum to 100, so the answer is D.
