ANSWER

Answer:-

The cumulative frequency Table is:-

Class Frequency Cumulative frequency

0-5 10 10

5-10 15 25

10-15 12 37

15-20 20 57

20-25 9 66

Here,

N

=

66

=33

Thus 37 is just greater than 33,

∴ The median class is "10−15."

The lower limit of the median class is 10.

Modal class = class with maximum frequency.

∴ Modal class is 15−20.

The lower limit of the modal class is 15.

Sum of lower limits of median class and modal class = 10+15=25
