      Question

       If the price of sugar increases by 40%, by what

      percentage should a family reduce its sugar consumption so that the family's expenses do not increase?
      A 18(4/7) %. Correct Answer Incorrect Answer
      B 23(4/5) %. Correct Answer Incorrect Answer
      C 28(4/7) %. Correct Answer Incorrect Answer
      D 20(4/9) %. Correct Answer Incorrect Answer

      Solution

      When price increases by r% then consumption is reduced by (r/r+100) ×100% and Expenses will remain the same. r = 40% (increase in price) Reduction in consumption = (40/140) x 100 =400/14 =28(4/7) %.
