Set S is composed of consecutive multiples of 3. Set T is composed of consecutive multiples of 6. Each set contains more than one element. Is the median of set S bigger than the median of set T?

1. The least element in either set is 6
2. Set T contains twice as many elements as set S

from ( 1 ) you can't answer because it may or may not be bigger, but if you know ( 2 ) as well as ( 1 ) then you can answer the question.

Thus "C"

S can be 300, 303, 306

OR

T can be 6, 12, 18, 24, 30, 36

1. The least element in either set is 6
2. Set T contains twice as many elements as set S

1: Do not know the no of elements in each set.
2: do not know whether S or T has -ve or +ve elements.

1&2: sufficient as we know the first elelment is 6 and T has twice as many.

so Median T > Median S.

good one.
