It's math day, and that means MGRE Math Beast Challenge problems! Check out how right I was with last week's MGRE problem, and while you're at it, check out this week's problem (warning: my solution is already in the comments, so don't peek if you're aiming to solve the problem yourself). Have fun. This week's problem is one for which you have to provide the answer: there's no multiple choice. The new GRE has many such problems now; I'm glad to see MGRE providing practice in this area.
