Logic puzzles are not just fun; they’re an excellent way to keep your brain sharp and improve your problem-solving skills. Today, we’re diving into a tricky puzzle involving a referee, a whistle, and some shoes. Are you ready to take on the challenge and figure out the final equation?

What’s the Puzzle?

As seen in the image, the puzzle consists of several equations featuring shoes, a referee, and a whistle. The big question is: “What is the result of the final equation?” It might look simple at first glance, but there are details that could trip you up. Before reading the solution, give it a shot and see if you can solve it!

Common Mistakes When Solving the Puzzle

Many people make similar mistakes when tackling this puzzle. Here are a few things that often lead to incorrect answers:

1. Overlooking the Details:
One of the most common mistakes is not noticing that the referee appears with and without a whistle. This small detail can make a big difference in the final answer.

2. Ignoring the Order of Operations:
Just like in standard math problems, the order of operations is crucial. Multiplication must be done before addition, and failing to follow this rule will lead to the wrong answer.

Step-by-Step Puzzle Solution

Let’s solve this puzzle step by step to make sure we get it right.

Line 1: Figuring Out the Shoes

In the first equation, we have three pairs of shoes adding up to 30. Since there are three pairs, we can divide 30 by 3 to find the value of one pair:

3 pairs of shoes = 30 → 1 pair of shoes = 10
Therefore, each shoe equals 5.

Line 2: Decoding the Referee with a Whistle

The second equation shows two referees with whistles and one pair of shoes, which together equal 20. We already know the pair of shoes is worth 10. Subtracting this from 20 leaves us with 10, which is the combined value of the two referees with whistles:

Pair of shoes (10) + 2 referees with whistles = 20
2 referees = 10 → 1 referee with a whistle = 5

Line 3: Determining the Value of a Whistle

In the third equation, a referee with a whistle and two whistles together equal 13. We know the referee with a whistle is worth 5, so subtracting this from 13 gives us the value of the two whistles:

Referee with whistle (5) + 2 whistles = 13
2 whistles = 8 → 1 whistle = 2

Final Line: The Grand Calculation

Now, with all the values in hand, let’s solve the final equation. The equation includes one shoe (5), one referee without a whistle (3), and one whistle (2):

1 shoe (5) + 1 referee without a whistle (3) × 1 whistle (2)

According to the order of operations (multiplication before addition), we first calculate the multiplication:

3 × 2 = 6

Then, we add the value of the shoe:

5 + 6 = 11

Thus, the correct answer is 11.
