Solve this
The image shows a puzzle presented as a mock BMW company interview question. The task is to solve the equation "5 + 7 = 2" by moving only one matchstick to make it correct.
The solution to this puzzle is:
Move the vertical matchstick from the plus sign (+) and place it horizontally on top of the equals sign (=). This transforms the equation to:
5 - 7 = -2
Now the equation is mathematically correct, as 5 minus 7 indeed equals negative 2.
This puzzle is designed to test lateral thinking and problem-solving skills, encouraging candidates to think outside the box and consider non-obvious solutions. It's a clever way to assess a person's ability to approach problems creatively, which could be valuable in a company setting.
