Question

The lower limit of the median class of the following data is:
Class: 0-10, 10-20, 20-30, 30-40, 40-50
Frequency: 3, 9, 15, 30, 18

Accepted Answer

Total frequency $N = 3 + 9 + 15 + 30 + 18 = 75$. $N/2 = 37.5$. Cumulative frequencies are: 3, 12, 27, 57, 75. The cumulative frequency just greater than 37.5 is 57, which corresponds to the class 30-40. The lower limit is 30. Therefore, option C is correct.
