      A 115 Correct Answer Incorrect Answer
      B 85 Correct Answer Incorrect Answer
      C 70 Correct Answer Incorrect Answer
      D 60 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      As men and women are equal so , there are 4 women and 4 men so, total consumption will be 72×4 = 288(by men) and 50×4 = 200(by women)
      Total consumption = 488.
      But after including a woman the average consumption for 9 people is given to be 67.
      So the total consumption will be 67×9 = 603.
      So, woman’s consumption will be = 603 – 488 = 115
