(c) between Rs.1,500 and Rs.2,500

Answer 1

(i) Range = Largest Value -Smallest Value

Highest Value = 5090

Lowest Value = 1007

So, Range = 5090-1007 = 4083

(ii)

(iii) (a) Number of households whose monthly expenditure on food is less than Rs. 2000

=20+13 =33

(b) Number of households whose monthly expenditure on food is more than Rs. 2000
