Answer :


We may observe that the class intervals are not continuous. There is a gap between two class intervals so we have to add from lower class limit of each interval.


Class size (h) of this data = 3


Now taking 57 as assumed mean, we can calculate as follows:



Mean = A + * h


= 57 + * 3


= 57 +


= 57 + 0.1875 = 57.1875


= 57.19


Number of mangoes kept in packing box is 57.19
