The Correct Option is C
Solution and Explanation
The frequency table is obtained as follows: \[ \begin{array}{|c|c|} \hline \text{Class Interval (Marks)} & \text{Frequency (Number of Students)} \\ \hline 0 - 10 & 3 \\ 10 - 20 & 9 \\ 20 - 30 & 15 \\ 30 - 40 & 30 \\ 40 - 50 & 18 \\ \hline \end{array} \] The modal class is the class with the highest frequency. From the table, the highest frequency is 30, corresponding to the class interval $30 - 40$.

- Marks obtained by all the students of class 12 are presented in a frequency distribution with classes of equal width. Let the median of this grouped data be 14 with median class interval 12-18 and median class frequency 12. If the number of students whose marks are less than 12 is 18, then the total number of students is:
