The width of each of five continuous classes in a frequency distribution is 5 and lower class limit of the lowest class is 10. What is the upper class limit of the highest class?

Answer»

We know that lower limit of the lowest class = 10

It is given that

Width of each class = 5

Total number of classes = 5

So we get

First class = 10-15

Second class = 15-20

Third class = 20-25

Fourth class = 25-30

Fifth class = 30-35

Therefore, the upper class limit of the highest class is 35.
