21.875%

Let the initial price=100 and consumption=100, then initial expenditure=10000
When new price=128 and consumption=x, then new expenditure=128x
In order to keep expenditure same, comparing both expenses 128x = 10000
=> x=10000/128=78.125
=> x=78.125% of the initial.
So decrease in consumption required=100 - 78.125=21.875%
