Question

The median of the observations 11,12,14,18,x+2,20,22,25,61 arranged in ascending order is 21. Find the value of x
​

Answer 1

11,12,14,18,y+2,20,25,61

Median=21

Numberofobservations=8

Median=

2

n

+1

=4+1

=5

th

observation

y+2=21

y=19

Answer 2

Answer:

Step-by-step explanation:

Here no.of terms is 9(odd)

So,median = n+1/2 th term

10/2=5th term which is x+2

Given median is 21.

therefore, 21= x+2

So,x =19
