x,y (integers) >0, find y-?
st(1) x/y and 1/3 have least common denominator (LCD) OR
We must ascertain the lowest common multiplier (LCM) for y and 3 --> depending on y LCM can be anything- hence Not Sufficient;
We cannot choose LCM and LCD for y and 3 as 6 because y could be 9 then LCD=9; y could be 11 then LCD=33 ...
st(2) x=1 This information is irrelevant for our solution, as we need to know
y Not Sufficient;
Combined st(1&2): Not Sufficient, as we operate mainly with the only relevant condition in st(1) and this is not enough to answer this question.
answer E

1) The least common denominator of x/y and 1/3 is 6?
2) x = 1
OA is E. I chose A thinking y needs to be 6. Not sure what is wrong there.
