If X>7, then Median is 6.5
If Mean and Median is same, then the median is 5.5.

So E.

How come E......
stat 1 tells us if If X>7, then Median is 6.5 - Suff
Stat 2 tells us that The mean of the six numbers is equal to the median for which median would be either 5.5 for X=2 or 6.5 for X=8- Not suff
Ans should be A

got A for this one as well.

regardless of the value of x, after ordering the list from least to greatest, you see that the median is always 6.5

1). X>7
2). The mean of the six numbers is equal to the median.


THE MEDIAN IS THE AVERAGE OF THE 2 MIDDLE VALUES
THEN THINK OF THE NUMBERS AS 2 SET ( 4,5,6) ( 7,X,9) OR (7,9,X) EITHER WAYS 6,7 ARE THE MIDDLE ONES..............SUFF

FROM2

WE CANT DEDUCE THE LOCATION ( ORDER OF X) .......INSUFF

MY ANSWER IS THUS A
