daal is now being sold at rate Rs.20 a kg.During last month its rate was Rs 16 per kg.By How reduce percent should a family its consumption so as to keep the expenditure fixed?

• Last month rate= 16 per kg
  this month rate = 20 per kg
  if 20=100% then 16= ?
  therefore %= (16 * 100)/20=80%
  to reduce consumption 100-80=20%
  
  ans=20%

  Working with examples
  eg. let the family consume 5kg of Daal previous month.. so der total expenditure would be Rs 80.
  Now after the hike in price, dey can only buy 4kg of Daal keeping in mind the Constant factor of expenditure, which is 20% less to the previous month Quantity(i.e 5kg). So in order to Nullify that % the family will have to reduced their Consumption by 20%
