Question
The ratio of the number of cats and dogs in a pet store
is 7:3, respectively. If 50% of cats are Siamese and 70% of dogs are Labradors, find the ratio of the number of cats other than Siamese to the dogs that are not Labradors.Solution
ATQ, Required ratio = (0.5 × 7):(0.3 × 3) = 3.5:0.9 = 35:9
