Class size = 10
As class size is the difference between upper limit and lower limit
EX : 104 - 114
class size = 10
Class limit :  the lowest and highest marks which are included in a class are called lower class limit and upper class limits of the class.
Ex : 104 -114 
lower class limit is 104 and upper class limit = 114
