Question

the following terms are arranged in ascending order 10,13,14,16,x+2,x+4,27,30,33,38. If median of terms be 25 .Then find the value of X.

Answer 1

As there are 10 observations,

Median =  $\frac{ \frac{n}{2}+ \frac{n+2}{2} }{2}$

Median = $\frac{5th observation+ 6th observation}{2}$

Median = $\frac{x+2+ x+4}{2}$


25=  $\frac{2x+6}{2}$


25*2 = 2x +6 

50 = 2x +6

50 - 6 =2x

44 = 2x 

44/2 =x 

22 = x 



i hope this will help you
