Nobody knows “pie” like Pizza Hut, but this March 14, Pizza Hut is dropping the “e” in honor of Pi – 3.14 – everyone’s favorite irrational number.
In partnership with mathematical genius John H. Conway, a distinguished professor of mathematics at Princeton University, and in honor of “National Pi Day” on March 14, Pizza Hut released three math problems with a unique challenge: be the first person to solve and submit the correct answer to any one of the problems for a chance to receive 3.14 years of free pizza from Pizza Hut.
The questions are varying in level of difficulty from high school to PhD level. The problems were posted at 8:00 a.m. on Monday, March 14.
Math experts and Pizza Hut fans alike can visit the Hut Life blog at blog.pizzahut.com to view the Pizza Hut Pi Day math problems on Monday. Answers must be provided within the blog comments, which will be time stamped to determine the potential winner (fans can only win once).
Pizza Hut equates 3.14 years of free pizza to approximately $1,600 in gift cards from the pizza restaurant company.
Here they are:

OPTION A: – SOLVED – WINNERS WILL BE NOTIFIED WITHIN 24 HOURS
I’m thinking of a ten-digit integer whose digits are all distinct. It happens that the number formed by the first n of them is divisible by n for each n from 1 to 10. What is my number?
OPTION B: – SOLVED – WINNERS WILL BE NOTIFIED WITHIN 24 HOURS
Our school’s puzzle-club meets in one of the schoolrooms every Friday after school.
Last Friday, one of the members said, “I’ve hidden a list of numbers in this envelope that add up to the number of this room.” A girl said, “That’s obviously not enough information to determine the number of the room. If you told us the number of numbers in the envelope and their product, would that be enough to work them all out?”
He (after scribbling for some time): “No.” She (after scribbling for some more time): “well, at least I’ve worked out their product.”
What is the number of the school room we meet in?”
OPTION C: – YET TO BE SOLVED, No one has gotten this one exactly right yet! Hint: It helps to show your work!
My key-rings are metal circles of diameter about two inches. They are all linked together in a strange jumble, so that try as I might, I can’t tell any pair from any other pair.
However, I can tell some triple from other triples, even though I’ve never been able to distinguish left from right. What are the possible numbers of key-rings in this jumble?
