Since the maximum families 40 lies in the class 1500 – 2000, this is the required modal class. 

Lower boundary of the modal class (l) = 1500 

Frequency of the modal class (f1) = 40 

Frequency of the class preceding the modal class f0 = 24 

Frequency of the class succeeding the modal class f2 = 33 

Height of the class, h = 500 

Hence, modal monthly income = Rs. 1847.83. 

Assumed mean (a) = 3250
