Question

The sum of the lower limit and upper limit of the modal class from the given distribution table.

Class	10-20	20-30	30-40	40-50	50-60	60-70
Frequency	2	8	17	11	9	8

A) 90 

B) 110 

C) 70 

D) 50

Answer 1

Correct option is: C) 70

Since, highest frequency is 17 which is of the class 30-40.

\(\therefore\) Class 30-40 is the modal class of the data

Lower limit of the modal class = 30

Upper limit of the modal class = 40

\(\therefore\) Sum = 30 + 40 = 70

Hence, the sum of lower limit and upper limit of the modal class is 70.

Answer 2

Correct option is: C) 70
