Question 1. Asked on :13 January 2019:01:13:28 PM
Find the median of11,12,2x+2,3x,21,23 where x is the mean of 5,10,3.
-Added by Akki chauhan Mathematics » Probability
Answer:
We know,
if the number of observation (n) is even
then,
1. first of all find the value at the position
2. and find the value at the position
3. now find the average of two value to get the median .
e.g.,
Given, 11, 12, 14, 18, (x + 2), (x + 4) , 30, 32 , 35 , 41 are in ascending order .
number of terms = 10 {even}
so, median = {(n/2)th + (n/2 + 1) th }/2
24 = (5th + 6th)/2
24 = {(x + 2) + (x + 4)}/2
24 = (x + 3)
x = 21
hence, x = 21
