Demo class

Let L be the lower class boundary of a class in a frequency distribution and m be the midpoint of the class. Which one of the following is the upper class boundary of the class.

If the width of each of the ten classes in frequency distribution is 2.5 and the lower class boundary of the lowest class is 5.1, then the upper class boundary of the highest class IS

Let Ube the upper class boundary of a class in a frequency distribution and Mbe the mid-point of the class. Which one of the following is the lower class boundary of the class?

In a frequency distribution table with 12 classes, the class-width is 2.5 and the lowest class boundary is 8.1, then what is the upper class boundary of the highest class?

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. The upper class limit of the highest class is

Find the class mark of the class 35-39 . What is the next consecutive class ?

If class marks is 20 and class width is 6. Find the class.

If class mark is 15 and class widht is 10, then find the class.
