Dog , Cat and Rabbit Puzzle

Give me answer of this question ?

Cat + Rabbit = 10 kg

Dog + Rabbit = 20 kg

Dog + Cat = 24 kg

Dog + Cat + Rabbit = ?? kg

**Answer with Explanation :**

Lets say rabbit, cat and dog’s weight are R,C and D respectively.

Then by the given data :

Equation 1: R + C = 10

Equation 2: D + R = 20

Equation 3: C + D = 24

Now we need to find the value of C + R + D

On adding Equation 1,2 and 3

2R + 2C + 2D = 54

R + C + D = 27

Hence Weight of Rabbit + Cat + Dog = 27 kg
