If the average of n observation (where n is odd) in ascending order is a. The average of first `(n+1)/2` observations is b that of last `(n+1)/2` observation is c. then find the `((n+1)/2)^(th)` observation.

If the average of n observation (where n is odd in assending order is a.The average of first (n+1)/(2) observations is b that of last (n+1)/(2) observation is c.then find the ((n+1)/(2))^(th) observation.

The median of n observations arranged in ascending order when n is even

If the average of observations x,x +1,x+2,x+3 and x+4 is 12, then what is the average of the last three observations ?

AM of n observations is M.If the sum of (n-5) observations is R, then mean of remaining 5 observations is

Assertion : The median of the data 105, 103, 102, 107, 120, 124, 111 and 124 is 109 Reason : When the number of observations (n) is odd, then the median is the value of the ((n + 1)/(2))^(th) observation. If the number of observations (n) is even , then the median is the mean of the ((n)/(2))^(th) observation and the ((n)/(2) + 1)^(th) observation

If the mean of n observations is 5 and sum of observations is 25, then find n .

The average of 11 observations is 60. If the average of first five observations is 58 and that of the last five is 56, then the sixth observation is

Average of ‘n’ observations is 38, average of ‘n’ other observations is 42 and average ofremaining ‘n’ observations is 55. Average of all the observations is:

If the mean of n observations is 12 and the sum of the observations is 132, then find the value of n.
