Hi,
I have a hunch that you're the same person that has asked the 3 other quant questions!
I think you're approaching this wrong (if I may).
Rather than spamming the Q&A to get the answer, you need to learn the logic.
Same goes with case types (you can't just memorize every case framework out there...you have to learn how to think about every case prompt individually).
So, I highly recommend you ernestly try to solve each of these problems on their own.Then, post here with your reasoning/thinking and then we can comment on that.
You're not going to ace the case by getting every answer to every question in the world. Rather, you'll learn by figuring out how to think about each one you see! Also, a coach can help you with this :)
