I too think I know the one you're talking about. I believe I eventually got the answer. I finished PM session with 30 minutes left to spare and had decided to skip question that until the end. After working through it about 10 different ways I actually think I got the correct answer. I hadn't seen that type of problem before in any of my studies. Wish we were allowed to discuss specifics. There were a couple problems where CFAi got me. I had pencilled in the correct answer only to second guess myself and go back to change it to what ultimately turned out to be wrong.
