Question

if the median of 3,6,7,10,x,x+4,19,20,25,28is 13 finf the value of x

Answer 1

According to me the answer is 18.
If it is wrong then calculation mistake may be there.
But process will be same.

Answer 2

Since here n is even therefore median = mean of (n/2)the and ((n+1)/2)the observation

Here n=10

So median = (5th + 6th)/2

13 = (x+x+4)/2

13 = x+2

x = 11
