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
