Direction for the following 3 (three) items: Consider the given information and answer the three items (69-71) that follow.

A, B, C, D, E, F and G are Lecturers from different cities—Hyderabad, Delhi, Shillong, Kanpur, Chennai, Mumbai and Srinagar (not necessarily in the same order) who participated in a conference. Each one of them is specialized in a different subject, viz. Economics, Commerce, History, Sociology, Geography, Mathematics and Statistics (not necessarily in the same order). Further

1. Lecturer from Kanpur is specialized in Geography.
2. Lecturer D is from Shillong.
3. Lecturer C from Delhi is specialized in Sociology.
4. Lecturer B is specialized in neither History nor Mathematics.
5. Lecturer A who is specialized in Economics does not belong to Hyderabad.
6. Lecturer F who is specialized in Commerce belongs to Srinagar.
7. Lecturer G who is specialized in Statistics belongs to Chennai.

Who is specialized in Geography?

Correct Option: B

To determine who is specialized in Geography, let us analyze the given information step-by-step to map each lecturer with their respective city and subject specialization.

Given Details:
Lecturers: A, B, C, D, E, F, G
Cities: Hyderabad, Delhi, Shillong, Kanpur, Chennai, Mumbai, Srinagar
Subjects: Economics, Commerce, History, Sociology, Geography, Mathematics, Statistics

Step-by-step Deduction:

1. From statement 3: Lecturer C is from Delhi and specialized in Sociology.
2. From statement 6: Lecturer F is from Srinagar and specialized in Commerce.
3. From statement 7: Lecturer G is from Chennai and specialized in Statistics.
4. From statement 2: Lecturer D is from Shillong.
5. From statement 5: Lecturer A is specialized in Economics and is not from Hyderabad.
6. From statement 1: The lecturer from Kanpur is specialized in Geography.

Let us compile the direct information into a table so far:

• A: Economics | Not Hyderabad (Possible cities left: Kanpur, Mumbai)
• B: Subject unknown | City unknown
• C: Sociology | Delhi
• D: Subject unknown | Shillong
• E: Subject unknown | City unknown
• F: Commerce | Srinagar
• G: Statistics | Chennai

Assigning Cities and Subjects to remaining lecturers:

• The available subjects are Economics, Commerce, History, Sociology, Geography, Mathematics, Statistics.
• Subjects already assigned: Sociology (C), Commerce (F), Statistics (G), Economics (A).
• Remaining subjects to assign: Geography, History, Mathematics.
• Remaining cities to assign: Kanpur, Hyderabad, Mumbai.

Now consider Statement 1: The lecturer specialized in Geography must be from Kanpur.
- Lecturer A is specialized in Economics, so A cannot be from Kanpur.
- Lecturer D is from Shillong, so D cannot be from Kanpur.
- Lecturers C, F, G are already assigned to Delhi, Srinagar, and Chennai respectively.
- Therefore, the lecturer from Kanpur (who is specialized in Geography) must be either B or E.

Let us look at statement 4: Lecturer B is specialized in neither History nor Mathematics.
- The remaining subjects for B are Geography, History, or Mathematics.
- Since B cannot be specialized in History or Mathematics, Lecturer B MUST be specialized in Geography!

Hence, Lecturer B is specialized in Geography (and belongs to Kanpur).

Therefore, B is specialized in Geography.
