The correct Answer is:
To find the modal class from the given frequency distribution, we will follow these steps: ### Step 1: Identify the classes and their corresponding frequencies The frequency distribution provided is: - Marks: 0-10, 10-20, 20-40, 40-50, 50-60, 60-70, 70-90, 90-100 - No. of students (frequency): 4, 6, 14, 16, 14, 8, 16, 5 ### Step 2: Determine the frequency of each class From the data, we can summarize the frequencies as follows: - 0-10: 4 - 10-20: 6 - 20-40: 14 - 40-50: 16 - 50-60: 14 - 60-70: 8 - 70-90: 16 - 90-100: 5 ### Step 3: Identify the highest frequency Now, we will look for the highest frequency among the classes: - The frequencies are: 4, 6, 14, 16, 14, 8, 16, 5 - The highest frequency is 16. ### Step 4: Determine the modal class The classes that correspond to the highest frequency (16) are: - 40-50 (16 students) - 70-90 (16 students) Since there are two classes with the same highest frequency, we can consider the first one that appears in the list as the modal class. ### Conclusion Thus, the modal class is **40-50**. ---
