The following dat

Answer :

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


So, modal class monthly expenditure was Rs. 1847.83

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


h= 500, A=2750


(x̅) mean =

(x̅) =



So, mean monthly expenditure was Rs. 2662.50
