if the price of sugar increases by 28%, What should be the percentage decrease in consumption of sugar of that expenditure remains constant?

• 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%
