      Question

      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 Ă— 3 = 108
