In a set of evenly spread integers (odd number of integers of course) , the median = mean.
So in this case, we know this a set where the numbers are evenly spread, since they are all multiples of 3; 3,6,9,12,15...... But statement 1 alone isn't sufficient.
The second statement states that the median = 33. This statement alone doesn't tell us anything about the mean. But together we know that the numbers are evenly spread and the median is 33 and the numbers in the set are odd, so 33 is the median and the mean.
Hence C.
