For the following distribution

the sum of lower limits of the median class and modal class is

A

15

B

25

C

30

D

35

Text Solution

Verified by Experts

The correct Answer is:
B
Here,

Now, `(N)/(2)=(66)/(2)=33`, Which lies in the interval 10-15. Therefore, lower limit of the mediuan class is 10. The highest frequency is 20, which lies in the interval 15-20. Therefore lower limit modal class is 15. Hence, required sum is 10+15=25.
