Answer:
8 / 69
Explanation:
Fraction = Net rice sales / Total consumption expenditure
Fraction = 8 / 69
Working
Total Income = 100 ( In which he saves 40 % and spend 60 % which is left )
Net Rice sales = New - Old
Net Rice sales = (40*1120%) - 40
Net Rice sales = 48 - 40
Net rice sales = 8
Total consumption expenditure = New + Old
Total consumption expenditure = (60 x 15%) + 60
Total consumption expenditure = 9 + 60
Total consumption expenditure = 69
