Answer / vish

Another classic example of people replying to the queries
in hurry..the answer #1, #2, #3, #4 & #7 are WRONG ANSWERS.
Answer #6 is correct. Answer #5 also seems to be correct to
me (unfortunatley I can't run & verify it at the moment,
someone please verify it & let everyone know).

Ram.g, FYI..EXISTS clause just denotes whether query after
EXISTS clause returned any row or not, it NEVER give a
count of the number of rows returned. Here need to find if
there are more than one rows (i.e count is needed) so
EXISTS can't be used here.
