    Question

    A kennel has 40 dogs, and the food available is enough for

    15 days. If 10 more dogs are added, how long will the food last?
    A 5 days Correct Answer Incorrect Answer
    B 4 days Correct Answer Incorrect Answer
    C 6 days Correct Answer Incorrect Answer
    D 12 days Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let food lasts for 'T' days after adding 10 more dogs.

    ATQ,

    (40 × 15) = (40 + 10) × T

    Or,

    600 = 50 × T

    T = 600 / 50 = 12

    Therefore, food will last for 12 days after including 10 more dogs.
