    Ratio of cats to dogs in a shelter is 4:3. If 16 cats

    are adopted and 20 more dogs arrive, their numbers become the same. What was the initial number of dogs?
    A 148 Correct Answer Incorrect Answer
    B 174 Correct Answer Incorrect Answer
    C 108 Correct Answer Incorrect Answer
    D 182 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the number of cats and dogs be '4n' and '3n', respectively.

    So, 4n - 16 = 3n + 20

    Or, 'n' = 36

    Therefore, number of dogs = 36 × 3 = 108
