Show Answer

Correct Answer :

Option B

Tuesday - Math

Solution :

The correct option is Tuesday - Math.


Let's analyze the given information step-by-step to find the complete presentation schedule from Monday to Sunday:


1. Days of the week: Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday.


2. Placement of A: "A presents History on Monday."
- Monday: A (History)


3. Placement of E: "Three presentations are scheduled between A and E, who presents Music."
- Since A is on Monday, three days between are Tuesday, Wednesday, and Thursday.
- Therefore, E presents Music on Friday.
- Friday: E (Music)


4. Placement of F: "...F, who presents Geography on Saturday."
- Saturday: F (Geography)


5. Placement of B: "The number of students presenting before B is the same as the number of students presenting after F..."
- F presents on Saturday, so exactly 1 student presents after F (on Sunday).
- Therefore, exactly 1 student must present before B, which means B presents on Tuesday.
- Tuesday: B


6. Placement of Civics: "Four students present between B and the one who presents Civics."
- B is on Tuesday, so four days between are Wednesday, Thursday, Friday, and Saturday.
- Therefore, Civics is presented on Sunday.
- Sunday: (Civics)


7. Placement of C and D: "C presents immediately after the one who presents Math, and immediately before D, who presents Art."
- This means the order must be: (Math) → C → D (Art).
- The only three consecutive available slots for this sequence are Tuesday, Wednesday, and Thursday.
- Therefore:
• Tuesday's subject must be Math (since B presents on Tuesday, B presents Math).
• C presents on Wednesday.
• D presents Art on Thursday.
- Tuesday: B (Math)
- Wednesday: C
- Thursday: D (Art)


8. Remaining Student and Subject:
- The only remaining student for Sunday is G.
- The only remaining subject for Wednesday (C's presentation) is Science.


Final Schedule:
- Monday: A - History
- Tuesday: B - Math
- Wednesday: C - Science
- Thursday: D - Art
- Friday: E - Music
- Saturday: F - Geography
- Sunday: G - Civics


Comparing the final arrangement with the options, the true combination is Tuesday - Math.
