Hello
Given,
Number of observations = n = 10
Since n is even
Median = ((n/2)th obversation + (n/2 + 1) th obversation)/2
Median = (5th + 6th observation)/2
Median = [(x + 1) + (2x - 13)]/2
Median = [3x - 12]/2
24 = [3x - 12]/2
24(2) = 3x - 12
48 = 3x - 12
3x - 12 = 48
3x = 48 + 12
3x = 60
x = 60/3
x = 20
