  1. *1Data of 24 households out of the 84 households were omitted from this analysis of Table 2 due to some loss of data
  2. *2Number of consumers per household was calculated using the formula of Richards and Widdowson (1937). One consumer is defined to be equal to a man whose age is above 15 years, a woman above 15 years is equal to 0.8, a child whose age from 7 to 15 years is equal to 0.7 and a child from 2 to 7 years is equal of 0.5 of a consumer
