x, 3, 1, 12, 8

If x is an integer, is the median of the 5 numbers shown greater than the
average (arithmetic mean) of the 5 numbers ?

(1) x > 6

(2) x is greater than the median of the 5 numbers.

IMO E

X is greter than median, hence x can not be median - which makes 8 as median

X can be any thing greter than 8 (greter than 12 too...)

let's say 9 - which makes mean as 31/5, which is lesser than median
let' say 13 - which makes mean as 7, which is lesser than median
let's say 22 - which makes mean as 46/5, which is greter than median

unconsistent results and hence E
I am I
