Question

find the median of the following observations arranged in ascending order is 15
10,12,14,x-3,x,x+2,25
Then find x

Answer 1

DEAR FRIEND THE SOLUTION IS HERE:

Number of terms = 7=n

Median=15 (given in question)

The terms in the question are odd so,

the median is " [n+1]\2 "th term.

Median=(7+1)/2 th term

= 4th term

According to the problem:

x-3 = 15

x= 18

Therefore the value of x is 18.

Answer 2

there are 7 terms  

now the ascending order is 10,12,14,x-3,x,x+2,25      

then meadian comes at 4th

x-3 =15

x =18
