Chopping on Chopin & Marvelous with Math
After six rounds, Yiwen C, Allard ‘20, with 30 of a possible 30 points, is currently the top student in the Math Department’s fortnightly challenge. She is also a very accomplished pianist who performed at the Cowichan Music Festival Gala concert on Sunday at the Duncan United Church where she will be performed Frederic Chopin’s “Minute Waltz”. Yiwen also received a cash award for Promising Intermediate Performance.
If you’d like to take a stab at this week’s math challenge (Yiwen no doubt already has) please email your answers to email@example.com
Here is the problem. Do you have a solution? ;-)
You have two cups, equal size. One is near full with black coffee. One is near full with cream. You take a spoonful of cream from one cup and pour it into the coffee, then mix well. There is room in the cup to do this. You then take a spoonful from the coffee/cream mixture, and pour it into the cream cup.
Question: Which cup is more “pure”? i.e., which cup has the higher proportion of its original content?
