See the given picture. Can you find out the combined weight of Cat, Dog and Rabbit?
Let us use equations to solve this puzzle.
Rabbit + Cat = 10 Kg ---- Eq. 1
Dog + Rabbit = 20 Kg ---- Eq. 2
Cat + Dog = 24 Kg ---- Eq. 3
Now add all the three equations
2(Cat) + 2(Dog) + 2(Rabbit) = 10 + 24 + 24
2 (Cat + Dog + Rabbit) = 54
Cat + Dog + Rabbit = 27.
