Think you have a sharp mind? This challenging brain teaser is making the rounds, and only a few can solve it without peeking at the solution. The puzzle requires you to analyze a series of equations and identify the missing number. But beware—many people fall into common traps when attempting to solve it.
Take a moment, study the equations, and try to crack the code before reading ahead. Can you figure it out?
Can You Replace the Question Mark with the Correct Number?
This is more than just a simple math puzzle—it’s a test of logical reasoning and pattern recognition. At first glance, the equations may seem straightforward, but the trick lies in understanding how the numbers relate to each other.
Here’s the puzzle:
Wrench + Wrench + Wrench = 15
Wrench + Gear + Gear = 25
Gear – 2 Bolts = 8
Bolt + Wrench × Gear = ?
The goal is to determine the missing number. Take a few moments to solve it before scrolling down to the answer!
Common Mistakes When Solving the Puzzle
Many people make quick assumptions when approaching problems like this, leading to incorrect answers. Here are some of the most common mistakes:
-Ignoring Order of Operations – Remember, multiplication always comes before addition and subtraction.
-Making Wrong Assumptions About Object Values – Each object has a set value, and misinterpreting one equation can throw off the entire solution.
-Overlooking Consistency – Some assume the numbers change between equations, but they remain the same throughout.
If you made any of these mistakes, don’t worry! Let’s go through the step-by-step solution to see how it’s done.
Step-by-Step Solution to the Puzzle
Now, let’s break down the problem logically.
Step 1: Solving for the Wrench
The first equation is:
Wrench + Wrench + Wrench = 15
Since there are three wrenches, divide 15 by 3:
Wrench = 5
Step 2: Solving for the Gear
The second equation is:
Wrench + Gear + Gear = 25
We already know that Wrench = 5, so substitute it into the equation:
5 + 2G = 25
Now, solve for G (Gear):
2G = 25 – 5
2G = 20
G = 10

So, Gear = 10
Step 3: Solving for the Bolt
The third equation is:
Gear – 2 Bolts = 8
We now know that Gear = 10, so substitute it in:
10 – 2B = 8
Solving for B (Bolt):
2B = 10 – 8
2B = 2
B = 1
So, Bolt = 1
Step 4: Solving for the Final Equation
Now, let’s solve the last equation:
Bolt + Wrench × Gear = ?
Substituting the values we found:
1 + 5 × 10
Applying Order of Operations (PEMDAS/BODMAS Rule)
Multiplication comes first:
1 + (5 × 10) = 1 + 50 = 51
Final Answer: 51
So, the missing number is 51!
