Question 1
A student has 8 days to prepare for three exams: Computer Science, Chemistry, Mathematics. The required preparation days are:
- Computer Science: 1 days
- Chemistry: 2 days
- Mathematics: 3 days
If the student follows the optimal schedule starting today, on which day will the last exam be?
Step-by-step solution:
Timeline Planning Method:
1. Calculate total preparation time needed:
- Computer Science: 1 days
- Chemistry: 2 days
- Mathematics: 3 days
- Total: 6 days
2. Available days: 8 days
3. Extra buffer days: 2 days
4. Optimal schedule:
- Days 1-1: Prepare for Computer Science
- Day 2: Computer Science exam
- Days 3-4: Prepare for Chemistry
- Day 5: Chemistry exam
- Days 6-8: Prepare for Mathematics
- Day 9: Mathematics exam
Answer: The last exam will be on Day 8
Key Strategy: Schedule exams immediately after preparation period ends, accounting for all required prep days.
