Step-by-step explanation:

From the table, N/2 = 66/2 = 33, which lies in the interval 10 – 15.

Hence, lower limit of the median class is 10.

The highest frequency is 20, which lies in between the interval 15 – 20.

Hence, lower limit of modal class is 15.

Therefore, required sum is 10 + 15 = 25.

Hence, option (B) is correct

Answer 2

Answer: B (25)

Step-by-step explanation:

Lower limit of the median class

Class interval in which the median lies.

So, to see median we have to add 1 to the no.of terms. (Total Frequency) and divide it by 2.

(63 + 1) /2 = 64/2 = 32nd value is the median

10 + 15 = 25 (The place values of the terms when arranged in order)(second class)

25 + 12 = 37 (The place values of the terms when arranged in order)(third class)

32nd value lies between 25 and 37. Which means the median should be in 3rd class, which makes third class as median class.

So median class is  10-15.

Lower limit of 10 - 5 is 10

lower limit of the modal class

Modal class means the class which has the highest frequency.

So, here, 15-20 has the highest frequency of 20

So, 15-20 is the modal class

Lower limit of 15 - 20 is 15

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

10+15

=25

Answer B

Hope that it's understandable.
