Question 16 For the following distribution, the sum of the lower limits of the median and modal class is (a) 15 (b) 25 (c) 30 (d) 35
Modal class is class with highest frequency
∴ 15 − 20 is modal class
For Median class
N = Sum of frequency = 66
𝑵/𝟐= 33
∴ 10 − 15 is median class
Thus,
Lower Limit of Median Class = 10
Lower Limit of Modal Class = 15
Therefore,
Sum of Median and Modal Class = 10 + 15
= 25
So, the correct answer is (b)
