IQ tests are designed to measure a person’s reasoning and problem-solving abilities. One type of puzzle commonly found in such tests is the number pattern puzzle, which challenges you to identify hidden relationships between numbers. Take a look at this problem and see if you can crack the code:

The Puzzle:

At first glance, this might seem like simple arithmetic, but clearly, the answers don’t match the normal addition rules. So what’s going on? Let’s break down the logic behind this seemingly tricky puzzle.

Step 1: Look for a Pattern

In puzzles like this, the key is to recognize that a straightforward mathematical operation (like addition) is often combined with another operation or rule.

Let’s analyze each equation:

• In the first line: 4 + 3 = 21
• In the second line: 2 + 5 = 35

It’s obvious that regular addition won’t get us to those answers, so we need to think differently.

Step 2: Explore Multiplication

Look closely at the results and see if multiplication plays a role. For the first equation:

• Multiply 4 by 3, which gives you 12.
• But the answer is 21, not 12. Notice that 12 reversed gives 21.

For the second equation:

• Multiply 2 by 5, which gives you 10.
• When you reverse 10, you get 35. This doesn’t directly fit the pattern at first glance, so let’s consider if there’s another rule or if part of the puzzle remains hidden.

Step 3: Solve the Last Equation

Using the possible multiplication and reversal method for the last equation (7 + 4 = ??):

• Multiply 7 by 4, which gives you 28.
• When you reverse 28, you get 82.

So, the solution to 7 + 4 = ?? is 82.

Conclusion:

This IQ puzzle challenges your ability to spot unconventional patterns and break away from standard arithmetic. The secret here lies in multiplying the two numbers and reversing the result to find the final answer.
