The correct option is C Pocket ExpenseNumber of Students60−70670−80580−90790−1005100−1103110−1204
Count the number of students in each class interval and form the table as shown below.
Weekly expensesNumber of Students60−70670−80580−90790−1005100−1103110−1204
In the above frequency table the classes are continuous. So, the values that belongs to a class should be greater than or equal to the lower class but shold be less than the upper class.
Example: The value 80 will belong to the class 80-90 but not in 70-80.
