Question

the median of the following observation arranged in descending order is 25 find the value of x if observations are 50,42,35,2x+10,2x-8,12,11,8,6​

Answer 1

Answer:

Given numbers

50,42,35,2x+ 10,2x− 8,12,11,8,6

Median is 25 __(I)

Here we observe that

No. of observation is odd i.e.

n=9

So median is (2n+1) th term

from (I) 5 th

term from data is2x−8

Median=(29+1) thterm

25= 5 th

25= 2x− 8

2x= 25+ 8

2x= 33

x= 33/2

x= 16.5

x value is 16.5
