#### The median of the following observations arranged in ascending order,is 25.Find x. 11,13,15,19,x+2,x+4.30,35,39,46



Given observations in ascending order are: 11,13,15,19,x+2,x+4,30,35,39,46
Therefore the median is the average of (x + 2) and (x + 4)
Median = (x +2 + x + 4)/2 = x + 3
Given median = 25
