Answer 1

Answer:

Increased Consumption = 62 kg

Step-by-step explanation:

Let say Price of Sugar  =  P rs / Kg

Consumption of Sugar  = C  kg

Expenditure = CP   Rs

price of sugar is decrease by 25%

=> Price of Sugar = P - (25/100)P = 0.75P  rs/kg

family purchase 12 kg more sugar

=> Consumption of sugar = C + 12 kg

Expenditure = (C + 12) 0.75P   = 0.75CP  + 9P  Rs

expenditure decrease by 7%

=> CP - (7/100)CP  = 0.93CP  Rs

0.93CP =  0.75CP  + 9P

=> 0.18CP = 9P

=> C = 50

Consumption of sugar was 50 kg

Increased Consumption = 50 + 12 = 62 kg

Increased Consumption = 62 kg
