Solution- Find the weight of the cat, dog and rabbit
You are asked to find the combined weight of cats, dogs and rabbits in this brain game. Here is the solution to the brain teaser:
Let the cat’s weight be C, the dog’s weight be D, and the rabbit’s weight be R.
Now, C + R = 10
D + R = 20
D + C = 24
C + D + R = ???
Let’s use the first equation and find the value of C.
C = 10 – Rs
Moving on to the second equation, find the value of D.
D = 20 – Rs
Now, substitute the values of C and D into the third equation.
(20 – R) + (10 – R) = 24
=> 20 + 10 – R – R = 24
=> 30 – 2R = 24
=> 6 = 2R
=> 3 = Rs
So the weight of the rabbit is 3 kg.
Substitute the rabbit’s weight into the final equation.
(C + D) + R = ?
=> 24 + 3 = ?
=> 27
So the total weight of the cat, dog and rabbit is 27 kg.
Alternatively, you could substitute the weight of the rabbit into the first two equations and find the weights of the cat and the dog, then use them to solve the fourth equation.
You will see that the cat weighs 7 kg and the dog weighs 17 kg.
We hope you enjoy this tricky puzzle. Try your hand at this:
