Sally started a new semester at school this week and she’s having a bit of trouble. Her whole class schedule has changed and she’s still trying to remember it. The school day has six class periods in it, referred to as Period 1 through Period 6. That would be simple enough to remember, but then there are three different buildings that her classes might be held in – Grant Building, Roosevelt Building, and Washington Building - and of course, each building has three floors of classrooms. Thankfully, her classroom numbers were all even numbers between 2 and 12, and all the numbers were different – otherwise she’d really be confused! Determine what subject Sally had in each Period, and the building, floor, and classroom number where each class was held.
1. Sally had two classes on different floors in each building. Her first floor classes were the class in the Washington building and her algebra class. Her Period 2 class was held in classroom 10, but it wasn’t Spanish.
2. Classroom 6 is in the Roosevelt building, but she didn’t go to that classroom for a math or science class. Period 4 was her English class, which wasn’t held on the 2nd floor.
3. During Period 6, she was in the Grant building, but the classroom number was less than eight. She went to the Roosevelt building during Periods 1 and 3.
4. Band practice was in classroom 4, but not during Period 5. Classroom 12 was on the 3rd floor, but she didn’t go to that classroom for a language class.
5. The classroom number for her Spanish class was two higher than the 2nd floor classroom in the Grant building. Her algebra class was held during Period 1.
6. Her chemistry class was on the third floor, but the classroom number was four numbers higher than her Period 1 class. Her US History class was on the third floor, but not in the Washington building.
