Answer 2

Answer:

Step-by-step explanation:The price of the pulse increased by 30%

Final price of rice=1.3x

Now, expenditure=price×consumption

Let the final consumption bez

Therefore,z=(y/1.3)

%Decrease=((initialconsumption-final consumption))/initial consumption×100%

Therefore,% decrease=((y-z/y)×100%

=(1-(1/1.3))×100%=(1-0.769)×100%
