Here’s another chance to see if you can solve Anirban DasGupta’s three problems, which are on diverse topics. He says, “You can send a solution to just one, but we would be delighted if you send more! We hope you will enjoy thinking about the different things in these problems.”

See the three parts of Student Puzzle 58 here. The deadline is November 1, 2025.

Student members of IMS are invited to submit solutions to bulletin@imstat.org (subject “Student Puzzle Corner”). If correct, we’ll publish your name (and photo, if there’s space) with the solution in the next issue. The Puzzle Editor is Anirban DasGupta. His decision is final.
