Brain Teaser Solution

Let the 1st dog be A, 2nd dog be B and the third dog be C. 

As per the first equation,

A + B = 10 kg

=> B = 10 - A

According to the second equation, 

C + B = 20 kg

Let’s substitute the value of B in this equation, 

=> C + 10 - A = 20

=> C - A = 10

=> C = 10 + A

According to the third equation, 

C + A = 24 kg

Substituting the value of C in this equation, 

10 + A + A = 24 

=> 2A = 14

=> A = 7

Similarly, we can find the value of B and C by substituting the value of A = 7 in the above equations. 

A = 7

B =  3

And C = 17

Now, we need to find the weight of all three dogs combined, 

A + B + C =?

7 + 3 + 17 = 27

Hence, the combined weight of the three dogs is 27 kg.

If you were able to guess the answer, congratulations! And if you were unsuccessful, better luck next time!

We hope that you had fun solving this brain teaser.
