The average of `10` observations is `14.4`. If the average of first `4` observations is `16.5`. The average of remaining `6` observations is:

The mean of 10 observations is 12. If mean of first 6 observations is 13. Find the mean of remaining 4 observations.

The mean of 10 observations is 12. If mean of first 6 observations is 13. Find the mean of remaining 4 observations.

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:

The A.M. of n observations is M. If the sum of n - 4 observations is a, then the mean of remaining 4 observations is :
