The cumulative frequency of a class in a frequency distribution is the sum of the frequencies of that class and all previous classes.

Given that the total number of observed values in the frequency distribution is 50, and the frequency of the given class (25-30) is 10, we can subtract the frequency of the given class from the total number of observed values to find the cumulative frequency of all classes above the given class.

So, 50 (total observed values) - 10 (frequency of given class) = 40.

However, we are also given that the cumulative frequency of all classes above the given class is 40. This means that there are no other classes above the given class, and the cumulative frequency for the given class is the same as its frequency, which is 10.

So, the cumulative frequency for the class 25-30 is 10.
