1) A is sufficient. No need to explain. 2)insuff. Elements of A = only in A + both in A and B + both in A and C - in all the sets. same is for B and C. We will find the answer if we know the number of elements in only A or in only B or in only C.

A
Think i'm missing something... can anyone plot on a venn diagram to show A is sufficient?

HI , we dont even require any venn diag as the statement I itself gives the ans.... boeinz, sI 'Of the 16 elements in both A and B, 9 elements are also in C.' .... so it tells us that there are 9 elements in common to all three _________________

Thanks chetan2u! I mistook "16 elements are in both A and B" for "A U B".
