To maintain the same expenditure, the family should reduce consumption by 20%. If the price increases by 25%, the new price is 125% of the original. To find the reduction percentage, divide the original 100% by the new price percentage (125%) and subtract from 1, then multiply by 100 to get the percentage: (1 - (100/125)) * 100 = 20%.
