Weekly Problem 4 - 2009

Stage: 3 Short Challenge Level: Challenge Level:1

Tailor.

Bilbo and Frodo are essentially counting 1 through 8 and then going round again (with Tinker = 1, Tailor = 2, etc.). So if Bilbo finished on Sailor = 4 and Frodo finished on Poor Man = 6, then together they would reach $4+6=10$. But 10 is 2 after 8, and 2 = Tailor.

This problem is taken from the UKMT Mathematical Challenges.
