Logic puzzles are a great way to exercise your brain and improve your problem-solving skills. Today, we bring you a fun and tricky puzzle involving a referee and a whistle that will surely get you thinking. Are you ready to take on the challenge?
What’s the Puzzle?
As shown in the image above, the puzzle consists of several equations with images of shoes, a referee, and a whistle. The question is: “What is the result of the final equation?” Give it a try before reading the solution!
Common Mistakes When Solving the Puzzle
Many people tend to answer this puzzle incorrectly because they miss small but important details. Here are some common mistakes:
- Confusing the referee with a whistle and without a whistle: In the puzzle, the referee appears in two different forms: one wearing a whistle and one without. This small detail is often overlooked.
- Not following the order of operations: Just like in standard math problems, following the correct order of operations (multiplication before addition) is crucial. Failing to do so will lead to incorrect answers.
Step-by-Step Puzzle Solution
Let’s break down the puzzle step by step:
Line 1
There are three pairs of shoes, and their total value is 30. This means one pair of shoes equals 10, and each shoe equals 5.
3 pairs of shoes = 30 → 1 pair of shoes = 10 → 1 shoe = 5
Line 2
Two referees with whistles and one pair of shoes equal 20. Since we know the pair of shoes equals 10, the two referees must sum to 10. Therefore, each referee with a whistle equals 5.
Pair of shoes (10) + 2 referees with whistles = 20 → 2 referees = 10 → 1 referee with a whistle = 5
Line 3
One referee with a whistle and two whistles together equal 13. Since we know the referee equals 5, the two whistles must total 8. Thus, each whistle equals 2.
Referee with whistle (5) + 2 whistles = 13 → 2 whistles = 8 → 1 whistle = 2
Final Line
Now, we have all the information we need to solve the final equation: one shoe (5), one referee without a whistle (3), and one whistle (2). Substituting into the formula, we get:
1 shoe (5) + 1 referee without a whistle (3) × 1 whistle (2)
According to the order of operations (multiplication before addition), we calculate the multiplication first:
3 × 2 = 6
Then, add the value of the shoe:
5 + 6 = 11
Therefore, the correct answer is 11.
