Range of a given observations is `13.4` and the value of the lowest observation is `12.3,` then what will be the highest value of observation ?

Range of a given observations is 17 and maximum value of observation is 38, then find the minimum value of observation

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

The mean of 25 observations is 36. The mean of first 13 observations is 32 and that of last 13 observations is 39. What is the value of 13^(th) observation ?

The range of 12 observations is 60. If the least observation is 90, then find the greatest observation.

The median of 27 observations of a variable is 18.Three more observations are made and the values of these observations are 16,18 and 50 . What is the median of these 30 observations?

The mean of 5 observations is 3 and if one more observation is added, the mean becomes 3 . 5. Find out the value of new observation .
