# Consider the freq

Answer :

To find median class,

Assume Σfi = N = Sum of frequencies,

fi = frequency

and Cf = cumulative frequency So, N = 60

N/2 = 60/2 = 30

The cumulative frequency just greater than (N/2 = ) 30 is 37, so the corresponding median class is 160 - 165.

upper limit of median class = 165

For modal class,

Here, the maximum class frequency is 16.

The class corresponding to this frequency is the modal class. modal class = 150 - 155

lower limit of the modal class = 150

Hence, Sum of lower limit of the modal class and upper limit of the median class = 165 + 150 = 315
