    food and women eat on an average 40 kg of food. The men and women are equal in number. A woman joined the family for dinner and the average consumption became 55. How much did woman eat (in kgs)?
    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 3 women and 3 men so, total consumption will be 65 × 3 = 195 (by men) and 40 × 3 = 120 (by women)
    Total consumption = 315 kg
    But after including a woman the average consumption for 7 people is given to be 55.
    So the total consumption will be 55 × 7 = 385 kg
    So, woman’s consumption will be = 385 – 315 = 70 kg
