Cat and rabbit = 10 Dog and Rabbit = 20 Dog and Cat = 24 Cat weighs 4 more than Rabbit. 104=6, there are two animals so divide 6 by 2 = 3. Rabbit weighs 3, Cat weighs 7 (Rabbit (3) plus the 4 more the cat weighs = 7) Dog (?) and Rabbit (3) =20. 203=17, check by subtracting Cats weight from Dog and Cat, also get 17. Add 17+3+7=27. Any questions?
27. Cat is 7, bunny 3, dog 17
