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 of the following belongs to Hyderabad?

Here's a step-by-step breakdown: 1. **Identify direct assignments:** * C is from Delhi and specialized in Sociology. * F is from Srinagar and specialized in Commerce. * G is from Chennai and specialized in Statistics. * D is from Shillong. (Subject unknown) * A is specialized in Economics but not from Hyderabad. 2. **Use Clue 1 (Kanpur, Geography):** A lecturer from Kanpur is specialized in Geography. This means the person from Kanpur is the Geography specialist. 3. **Determine A's city:** * A is specialized in Economics. * A is not from Hyderabad (given). * A cannot be from Kanpur because Kanpur is for Geography (Clue 1). * The cities already assigned are Delhi, Srinagar, Chennai, Shillong. The remaining cities are Hyderabad, Kanpur, Mumbai. * Since A is not Hyderabad and not Kanpur, A must be from Mumbai. * So, A is from Mumbai and specialized in Economics. 4. **Identify remaining Lecturers, Cities, and Subjects:** * Lecturers remaining: B, E * Cities remaining: Hyderabad, Kanpur * Subjects remaining (for B, E, and D): History, Geography, Mathematics (Economics, Commerce, Sociology, Statistics are taken). 5. **Apply Clue 4 (B's subjects):** Lecturer B is specialized in neither History nor Mathematics. * From the remaining subjects (History, Geography, Mathematics), if B is neither History nor Mathematics, then B must be specialized in Geography. 6. **Determine B's city:** * If B is specialized in Geography, then according to Clue 1 (Lecturer from Kanpur is specialized in Geography), B must be from Kanpur. * So, B is from Kanpur and specialized in Geography. 7. **Determine E's city:** * All lecturers except E have been assigned a city (A-Mumbai, B-Kanpur, C-Delhi, D-Shillong, F-Srinagar, G-Chennai). * The only remaining city is Hyderabad. * Therefore, E must be from Hyderabad. The final answer is B) E.
