At first glance, this IQ test might seem daunting, but with a basic understanding of mathematics, anyone can solve it. The challenge lies in solving a series of equations where each symbol represents a specific value. Let’s dive into it and see if you can crack the code in just 20 seconds!
Breaking Down the Puzzle
The puzzle is straightforward once you understand the value of each symbol. Here’s the breakdown:
Line One: Oak Acorns
The first equation involves oak acorns:
- An acorn plus an acorn equals 18.
- Therefore, the value of one acorn is 9.
Line Two: Half Leaves
The second equation features half leaves:
- Half a leaf plus half a leaf equals 10.
- Thus, one half leaf is worth 5.
Line Three: Apples
The third equation uses apples:
- An apple plus an apple equals 16.
- Hence, the value of one apple is 8.
The Final Equation
Now, let’s put it all together in the final equation:
- An acorn plus a half leaf multiplied by an apple.
- Replacing the symbols with their respective values, the equation becomes: 9 + 5 x 8.
Solving the Final Equation
Here’s the tricky part. In mathematics, operations follow a specific order known as the order of operations (PEMDAS/BODMAS). Multiplication takes precedence over addition. So, we solve the multiplication first:
- 5 x 8 = 40
- Then, add the value of the acorn: 9 + 40 = 49
Therefore, the final answer is 49.
