Question

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.

• A. 15
• B. 25
• C. 35
• D. 40

Answer 1

The correct option is C

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.
