The width of each of the 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
Width of each class = 5 (given)
Total no. Of classes = 5 (given)
Lower class limit of lowest class = 10 (given)
Total width of class = 5 × 5 = 25
upper class limit of highest class = 10 + 25 = 35.
