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?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
