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
