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?

This is a logic puzzle that requires matching Lecturers, Cities, and Subjects. Let's break down the information step-by-step: Known facts from the statements: 1. C is from Delhi and specialized in Sociology. (C -> Delhi -> Sociology) 2. D is from Shillong. (D -> Shillong) 3. F is from Srinagar and specialized in Commerce. (F -> Srinagar -> Commerce) 4. G is from Chennai and specialized in Statistics. (G -> Chennai -> Statistics) 5. A is specialized in Economics and does not belong to Hyderabad. (A -> Economics, A != Hyderabad) 6. B is specialized in neither History nor Mathematics. (B != History, B != Mathematics) 7. The Lecturer from Kanpur is specialized in Geography. (Kanpur -> Geography) Let's list the remaining Lecturers, Cities, and Subjects after assigning the known facts: * Assigned Lecturers: C, D, F, G (A is partially assigned) * Remaining Lecturers to fully assign: A, B, E * Assigned Cities: Delhi, Shillong, Srinagar, Chennai * Remaining Cities: Hyderabad, Kanpur, Mumbai * Assigned Subjects: Sociology, Commerce, Statistics (Economics is assigned to A) * Remaining Subjects: History, Geography, Mathematics Now let's use statement 7: "The Lecturer from Kanpur is specialized in Geography." * Lecturer A is specialized in Economics, so A is not Geography. * Lecturer D is from Shillong, so D is not from Kanpur. * Therefore, the (Kanpur -> Geography) pair must be assigned to either Lecturer B or Lecturer E. Let's consider these two possibilities: Possibility 1: Lecturer B is from Kanpur and specialized in Geography. * This is consistent with statement 6 (B is neither History nor Mathematics, and Geography is neither of those). * So, B -> Kanpur -> Geography. Now, let's update the remaining items: * Lecturers to fully assign: A, D, E * Remaining Cities: Hyderabad, Mumbai (Kanpur is assigned to B) * Remaining Subjects: History, Mathematics (Geography is assigned to B) From statement 5: A is specialized in Economics and does not belong to Hyderabad. * Since the only remaining cities for A are Hyderabad and Mumbai, A must be from Mumbai. * So, A -> Mumbai -> Economics. Now, we have Lecturers D and E left, with City Hyderabad and Subjects History and Mathematics. * D is from Shillong (given). * Therefore, E must be from Hyderabad. (E -> Hyderabad) * The remaining subjects (History, Mathematics) must be assigned to D and E. * If D is History, then E is Mathematics. * If D is Mathematics, then E is History. This completes the puzzle without any contradictions. Possibility 2: Lecturer E is from Kanpur and specialized in Geography. * So, E -> Kanpur -> Geography. Now, let's update the remaining items: * Lecturers to fully assign: A, B, D * Remaining Cities: Hyderabad, Mumbai (Kanpur is assigned to E) * Remaining Subjects: History, Mathematics (Geography is assigned to E) From statement 5: A is specialized in Economics and does not belong to Hyderabad. * A must be from Mumbai. * So, A -> Mumbai -> Economics. Now, we have Lecturers B and D left, with City Hyderabad and Subjects History and Mathematics. * D is from Shillong (given). * Therefore, B must be from Hyderabad. (B -> Hyderabad) * The remaining subjects (History, Mathematics) must be assigned to B and D. * B's subject must be either History or Mathematics. * However, statement 6 clearly says: "Lecturer B is specialized in neither History nor Mathematics." * This creates a contradiction, as B must be one of these subjects. Therefore, Possibility 2 is incorrect. Conclusion: Possibility 1 is the only valid solution. In this scenario, Lecturer B is from Kanpur and specialized in Geography. The question asks: "Who is specialized in Geography?" Based on our valid solution, B is specialized in Geography. The final answer is A) B
