(i)The data may be presented in the form of an exclusive series :

(ii)Number of households spending less than Rupees 250 per month

Percentage of households spending less than Rs. 250 per month
`= 23/10 xx 100= 76.6%`
Number of households spending more than Rs. 200
`=13 +5+2= 20`
Percentage of households spending more than Rs 200 per month
`=20/30 xx 100= 66.6%`
