Question 1
A student has 9 days to prepare for three exams: Chemistry, Physics, Mathematics. The required preparation days are:
- Chemistry: 2 days
- Physics: 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:
- Chemistry: 2 days
- Physics: 2 days
- Mathematics: 3 days
- Total: 7 days
2. Available days: 9 days
3. Extra buffer days: 2 days
4. Optimal schedule:
- Days 1-2: Prepare for Chemistry
- Day 3: Chemistry exam
- Days 4-5: Prepare for Physics
- Day 6: Physics exam
- Days 7-9: Prepare for Mathematics
- Day 10: Mathematics exam
Answer: The last exam will be on Day 9
Key Strategy: Schedule exams immediately after preparation period ends, accounting for all required prep days.
