Question 1
A student has 8 days to prepare for three exams: Mathematics, Computer Science, Physics. The required preparation days are:
- Mathematics: 3 days
- Computer Science: 1 days
- Physics: 2 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:
- Mathematics: 3 days
- Computer Science: 1 days
- Physics: 2 days
- Total: 6 days
2. Available days: 8 days
3. Extra buffer days: 2 days
4. Optimal schedule:
- Days 1-3: Prepare for Mathematics
- Day 4: Mathematics exam
- Days 5-5: Prepare for Computer Science
- Day 6: Computer Science exam
- Days 7-8: Prepare for Physics
- Day 9: Physics 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.
