Median of the 5 sales = 330k
Ann total sales = 450k

Some part of Ann total sales need to be take away and the median should remain the same.
I think the for the value of the Ann total sales can change + or - the median, there by keeping the median constant.

So the value of the incorrectly recorded sales = 450 - 330 = 120K
