Are you ready to put your brain to the test? This challenging IQ quiz will surely sharpen your mind and make you think outside the box. Let’s dive right in.

To determine how many pieces were not sold, we need to follow a few simple steps. First, calculate the total number of pieces by considering that each pie is cut into eighths and there are 3 pies in total. This means that there are 24 pieces in all.

Next, we need to figure out how many pieces were sold. Given that three-quarters of all pieces were sold, we can calculate that 3/4 of 24 is equal to 18 pieces. So, 18 pieces were sold.

To find out how many pieces were not sold, simply subtract the number of pieces sold from the total number of pieces. In this case, 24 – 18 gives us 6 pieces that were not sold.

Therefore, the answer to this IQ quiz is that 6 pieces were not sold. This type of problem-solving exercise is not only a fun way to challenge yourself but also a great way to keep your mind sharp and improve your cognitive skills.
