The following data gives the distribution of total monthly household expenditure of 200 families of a village. Find the modal monthly expenditure of the families. Also, find the men monthly expenditure:

We may observe that the given data be maximum class frequency is 40 belonging to 1500- 2000 intervals

So, modal class = 1500- 2000


l=1500, f=40, f0=24, f2=33, h=50




=1500 + 347.826


=1847.826


So, modal class monthly expenditure was Rs. 1847.83


We may compute class marks (xi) as per the relation:



h= 500, A=2750



∑xi=200,




=2750-87.5


=2662.5


So, mean monthly expenditure was Rs. 2662.50
