Question

# Given the following distribution table:Class$$0-5$$$$5-10$$$$10-15$$$$15-20$$$$20-25$$Frequency$$10$$$$15$$$$12$$$$20$$$$9$$The sum of lower limits of the Median class and the Modal class is:

A
15
B
25
C
30
D
35

Solution

## The correct option is B $$25$$Answer:-The cumulative frequency Table is:- ClassFrequency Cumulative frequency  0-5 10 10 5-10 15 25 10-15 12 37 15-20 20 57 20-25 9 66Here, $$\cfrac{N}{2} = \cfrac{66}{2} = 33$$Thus $$37$$ is just greater than $$33$$, $$\therefore$$ The median class is "$$10-15.$$"The lower limit of the median class is 10.Modal class = class with maximum frequency.$$\therefore$$ Modal class is $$15-20.$$The lower limit of the modal class is $$15$$.Sum of lower limits of median class and modal class = $$10 + 15 = 25$$Mathematics
