    Question

    There is enough food in a camp to last for 25 days if

    each of the 40 soldiers present at the camp eat 4 times a day. After 15 days, 20 soldiers left the camp and remaining ate only twice a day. For how many days (from start) will the food last?
    A 30 days Correct Answer Incorrect Answer
    B 35 days Correct Answer Incorrect Answer
    C 40 days Correct Answer Incorrect Answer
    D 45 days Correct Answer Incorrect Answer
    E 55 days Correct Answer Incorrect Answer

    Solution

    Let the eating capacity of each soldier be 'x' units So, total food at the camp = (25 X 40 X 4 X x) = '4000x' units And food remaining after 15 days = 4000x - (15 X 40 X 4 X x) = '1600x' units So, required time = 1600x ÷ (x X 2 X 20) = 40 days So, the food will last for a total of 40 + 15 = 55 days
