A cumulative frequency distribution is given below:

Class	10-12	13-15	16-18	19-21	22-24
Cumulative frequency	3	8	15	2	33

Which one of the following class has maximum frequency?

Correct option is D

Given:

The cumulative frequency distribution is as follows:

Definition of Frequency:

The frequency of a class is calculated as the difference between the cumulative frequency of the current class and the cumulative frequency of the previous class.

Solution:

1. Calculate the frequencies for each class:

Frequency of 10-12 = 3 (no previous cumulative frequency).

Frequency of 13-15 = 8 - 3 = 5

Frequency of 16-18 = 15 - 8 = 7

Frequency of 19-21 = 20 - 15 = 5

Frequency of 22-24 = 33 - 20 = 13

2. Identify the class with the maximum frequency:

The class 22-24 has the maximum frequency of 13

Final Answer:

(D) 22-24
