Answer:
Given numbers
50,42,35,2x+10,2x−8,12,11,8,6 are in descending order
Median is 25 __(I)
Here we observe that
No. of observation is odd i.e. n=9
So median is (
2
n+1
)
th
term
from (I) 5
th
term from data is 2x−8
Median =(
2
9+1
)
th
term
25=5
th
term
25=2x−8
2x=25+8
2x=33
x=
2
33
x=16.5
x value is 16.5
