Test your IQ. Can you find out the weight of the cat, dog and rabbit in 15 seconds!

In the picture above you can see a cat, a dog and a rabbit on the scale.

The scale first reads the weight of the cat and dog. Their total weight is 10 kg.

The second scale reads the weight of the dog and the rabbit. Their total weight is 20 kg.

The third scale reads the weight of dogs and cats. Their total weight is 24 kg.

The fourth scale measures all three animals – the cat, the dog and the rabbit – but their combined weight is unknown. That’s what you have to discover.

What is the total weight of a cat, a dog and a rabbit? All the best! 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 — CHEAP

Moving on to the second equation, find the value of D.

D = 20 — CHEAP

Now substitute the values ​​of C and D in the third equation.

(20 — R) + (10 — R) = 24

=> 20 + 10 — R — R = 24

=> 30 — 2R = 24

=> 6 = 2R

=> 3 = CHEAP

So the weight of the rabbit is 3 kg.

Substitute the weight of the rabbit into the final equation.

(C + D) + R = ?

=> 24 + 3 = ?

=> 27

So, the total weight of a cat, a dog and a rabbit is 27 kg.
