Solution: Find the weight of the cat, the dog, and the rabbit.
You were asked to find the combined weight of the cat, dog, and rabbit in this puzzle. Here is the solution to the brain puzzle:
Let the weight of cat C, dog D, and rabbit R be.
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-R
Moving on to the second equation, let’s find the value of D.
d = 20-r
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 = R
So the weight of the rabbit is 3 kg.
Substitute the rabbit’s weight into the last equation.
(C + D) + R = ?
=> 24 + 3 = ?
=> 27
So the combined weight of the cat, dog and rabbit is 27 kg.
Alternatively, you can substitute the weight of the rabbit into the first two equations and find the weight of the cat and the dog, and then use them to solve the fourth equation.
You will find that the cat weighs 7 kg and the dog weighs 17 kg.
