Directions for the following 3 (three) items: Consider the given information and answer the three items 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?
(a) B · (b) D · (c) E · (d) Cannot be determined as data are inadequate
उत्तर और व्याख्या · explanation in English
Answer: (a) B
Once the direct clues are placed, History, Geography and Mathematics are left for B, D and E. Clue 4 rules out History and Mathematics for B, so B is the Geography lecturer (and hence the one from Kanpur).
- Direct clues: C – Delhi – Sociology; D – Shillong; F – Srinagar – Commerce; G – Chennai – Statistics; A – Economics.
- Cities left for A, B and E: Hyderabad, Kanpur, Mumbai. A is not from Hyderabad (clue 5), and Kanpur's lecturer teaches Geography while A teaches Economics — so A is from Mumbai.
- Subjects left for B, D and E: History, Geography, Mathematics. B teaches neither History nor Mathematics (clue 4), so B teaches Geography.
- Geography goes with Kanpur (clue 1), so B is from Kanpur, and the last city, Hyderabad, goes to E.
- D and E share History and Mathematics in some order — the data do not decide which.
- Geography: B.
Remember · In matching grids, place every direct clue first, then use 'neither/nor' and 'does not' clues to eliminate; the last blanks fall into place.
