Question 1

Five subjects are scheduled on five different days of the week (Monday to Friday), one subject per day. The following information is given: - Chemistry is scheduled on Wednesday - English is scheduled immediately after Biology - There are exactly two classes between Mathematics and History - Biology is not on Monday On which day is English scheduled?
Step-by-step solution:

Table Method:
1. Create a timeline for Monday to Friday
2. Apply direct constraints:
- Chemistry is on Wednesday (fixed)
- Biology is not on Monday
3. Apply consecutive constraint:
- English immediately follows Biology
- Possible pairs: (Tue-Wed), (Wed-Thu), (Thu-Fri)
- Since Wednesday is occupied, options are (Tue-Wed) or (Thu-Fri)
4. Apply gap constraint:
- Two classes between Mathematics and History
5. Final schedule:
- Monday: Mathematics
- Tuesday: History
- Wednesday: Chemistry
- Thursday: Biology
- Friday: English

Answer: English is scheduled on Friday
