The width of each of five continuous classes in a frequency distribution is 5 and the lower class - limit of the lowest class is 10.
Find the upper class - limit of the highest class.
35
Lower class limit of lowest class is 10.
As the width of each of five continuous classes is 5, the classes can be listed as given below:
10 - 15
15 - 20
20 - 25
25 - 30
30 - 35
Highest class is 30 - 35
Therefore, the upper class - limit of the highest class is 35.
