Above answer is wrong
So, it is right answer
n=10(even)
Median of n observations =24
[(n/2)term+(n/2+1)term]/2=24
[(10/2)term+(10/2+1)term]/2=24
5th term+6th term/2=24
(x+1)+(2x-13)/2=24
3x-12/2=24
3x-12=24*2
3x=48+12
X=60/3
X=20
Hence, the value of x=20

sorry value of x=24
I forget to multiply it by 2
the right answer is 20
