Psychopets
In a small country town, some of the pets were confused about their identities. 20% of the cats thought they were dogs while 20% of the dogs thought they were cats. The local veterinarian psychiatrist took a survey and found that 40% of all the cats and dogs thought they were cats. What percentage of all the cats and dogs were really cats?
Hint
Paws up all those who think they are a cat!Answer
Let there be x cats and y dogs.80% of x + 20% of y = 40%(x+y)
40% of x = 20% of y
2x = y
The number of dogs is double the number of cats.
Say there are 100 cats and 200 dogs. 33 1/3% of all of the animals are really members of the meow generation!
