    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 7 women and 7 men so, total consumption will be 65 × 7 = 455 (by men) and 40 × 7 = 280 (by women)
    Total consumption = 735 kg
    But after including a woman the average consumption for 15 people is given to be 55.
    So the total consumption will be 55 × 15 = 825 kg
    So, woman’s consumption will be = 825 – 735 = 90 kg
