Intelligence Test: Intelligence tests are often given to determine whether someone has a high or low intelligence quotient (IQ). The test measures a person’s cognitive abilities, that is, the ability to solve problems and reason logically.
There are several types of IQ tests, such as verbal, non-verbal, and full scale. These tests are usually exhaustive and tedious. Fortunately, there is also an exciting and fun way to test your IQ: brain teasers.
Brain teasers are probably the most fun and exciting way to measure a person’s logical thinking and problem-solving skills. And we have one ready for you.

Puzzle solution
Let the first dog be A, the second dog B, and the third dog C.
According to the first equation,
A + B = 10 kilos
=> B = 10-A
According to the second equation,
C + B = 20 kilos
Let’s substitute the value of B into this equation,
=>C+10-A=20
=> C – A = 10
=> C = 10 + A
According to the third equation,
C + A = 24 kilos
Substituting the value of C into 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 into the above equations.
One = 7
B = 3
YC = 17
Now we need to find the weight of the three dogs combined.
A + B + C =?
7 + 3 + 17 = 27
Therefore, the combined weight of the three dogs is 27 kg.
If you were able to guess the answer, congratulations! And if you didn’t make it, better luck next time!
We hope you had fun solving this brain teaser.
