Four university professors—Prof. Alok, Prof. Brinda, Prof. Chhaya, and Prof. Dilip—specializing in four distinct subjects (Economics, History, Political Science, and Sociology), are scheduled to present their research papers in four consecutive one-hour time slots: 9:00 AM, 10:00 AM, 11:00 AM, and 12:00 PM on the same day.
The following conditions govern their presentation schedule:
1. Prof. Alok presents immediately before the History specialist.
2. Prof. Brinda presents at 11:00 AM, but she is not the Sociology specialist.
3. The Economics specialist presents at 9:00 AM.
4. Prof. Dilip is the Political Science specialist and presents after Prof. Brinda.
Based on the information provided above, which of the following statements are correct?
- Prof. Chhaya is the Economics specialist and presents at 9:00 AM.Answer
- BProf. Alok specializes in History and presents at 10:00 AM.
- Prof. Brinda presents at 11:00 AM immediately after the Sociology specialist.Answer
- DProf. Dilip is scheduled to present his paper at 10:00 AM.
Answer
The statements confirming that Prof. Chhaya is the Economics specialist presenting at 9:00 AM and that Prof. Brinda presents at 11:00 AM immediately after the Sociology specialist are both correct.
Deducing the full schedule establishes: 9:00 AM - Prof. Chhaya (Economics), 10:00 AM - Prof. Alok (Sociology), 11:00 AM - Prof. Brinda (History), and 12:00 PM - Prof. Dilip (Political Science). Hence, the statement assigning Prof. Chhaya to 9:00 AM Economics and the statement noting Prof. Brinda presents right after the Sociology specialist (Prof. Alok at 10:00 AM) are both factually accurate.
