there are 29 children. 20 of them have a dog and 15 of them have a cat. how many have both a cat and a dog?
This is all the info given, I am assuming of the 29 children all of them either have a cat or a dog. If this is the case then I conclude that 6 children have both a cat and a dog. 14 + 6 = 20 (dogs) and 9+6 = 15 (cats) and 14 + 6 + 9 = 29 (total children)
Is this correct? If not can you please explain???
