1314.1: Logic Roommates
In my logic class, there are three sets of roommates, all living in doubles: Ashleigh, Belinda, Camille, Debra, Edna, and Farah. On a recent test, Ashleigh got a 96, Belinda got a 92, Camille got a 90, and Debra got an 84. Edna and Farah did not put their names on the test. When I first graded the tests, I only knew that their two scores were 88 and 86. I did not know which grade Edna received and which Farah received.
When Edna and Farah came to class and identified their papers, it turned out that two pairs of roommates had the same total grades. (To be clear: the total grade for a pair of roommates is the sum of their two grades.) Camille lives in South. Belinda lives in Babbitt. Debra's roommate had a lower grade than Edna's roommate.
1. Identify the three pairs of roommates.
2. What are Edna and Farah's scores?
