Direction : Study the following information carefully and answer the questions given below:
Eight persons are working in three different cities i.e. Delhi, Pune, Hyderabad. At least two persons are working in a city. There are four married couples of two generations. Number of males and females are equal in each city.
Note- Married couples are not working in same city. They have different designations i.e. GM, AGM, CEO, Manager, Assistant Manager, PO, Clerk, Sub staff (these are in decreasing order of seniority means GM is senior most and Sub staff is junior most person).
Only three persons are senior than the only son of B. B doesn’t work in Pune. E is sister in law of G who is junior most person. H is son in law of D, who is immediate senior of A. F is spouse of C and both are not working in Delhi. There are as many posts above father in law of A as below sibling of A. Only C and H are working in Hyderabad. Only PO and Sub staff are working in Delhi. Spouse of E is not working in Delhi. G is daughter in law of B who is spouse of D. F is senior than H and junior than C.

Correct answer: C
Concept
This is a combined puzzle: a single linear order of seniority (8 ranked posts), a city grouping, and a two-generation family tree must all hold at once. The technique is to fix the ABSOLUTE anchors first (a clue that pins an exact rank or an exact group), then use the family and city rules to place the rest. Two phrases are decisive here: "only N persons are senior than X" pins X's rank exactly, and "as many posts above P as below Q" means rank(P) and rank(Q) are mirror images about the list, i.e. (rank of P minus 1) equals (8 minus rank of Q).
Setting up the anchors
Ranks run 1 to 8 from senior to junior: GM, AGM, CEO, Manager, Assistant Manager, PO, Clerk, Sub staff.
"Only three persons are senior than the only son of B" puts B's son at rank 4 (Manager). The son's spouse is G (G is daughter-in-law of B), so the son is A; hence A = Manager (rank 4).
"G is the junior-most person" fixes G at rank 8 (Sub staff). "D is the immediate senior of A" puts D at rank 3 (CEO).
"Only PO and Sub staff work in Delhi" means the Delhi pair are exactly ranks 6 and 8 (each post is unique). G (rank 8) is one of them. B must take the other Delhi post: B is not in Pune, and Hyderabad holds only C and H, so B = PO (rank 6). City gender parity then makes B male and, in Hyderabad, C female with H male.
The two family couples
There are two parent couples, (B, D) and (C, F), and their children intermarry. A is the son of B and D; G is the daughter of C and F; H is the son of C and F; E is the daughter of B and D. So the married couples are (B, D), (C, F), (A, G) and (H, E). This is why the father-in-law of A is F: A married G, and G's father is F.
Using the mirror clue to finish the order
"As many posts above the father-in-law of A as below the sibling of A." Father-in-law of A = F; sibling of A = E. So (rank of F minus 1) = (8 minus rank of E).
Ranks 3, 4, 6 and 8 are already taken (D, A, B, G), so the four open ranks for C, F, H and E are 1, 2, 5 and 7. From "F is senior than H and junior than C" the order among them must keep C before F before H.
The mirror equation with C before F before H forces F = rank 2 (AGM) and E = rank 7 (Clerk): then above F = 1 and below E = 1, which match. That leaves C = rank 1 (GM) and H = rank 5 (Assistant Manager).
Final arrangement
Rank | Designation | Person | City |
|---|---|---|---|
1 | GM | C | Hyderabad |
2 | AGM | F | Pune |
3 | CEO | D | Pune |
4 | Manager | A | Pune |
5 | Assistant Manager | H | Hyderabad |
6 | PO | B | Delhi |
7 | Clerk | E | Pune |
8 | Sub staff | G | Delhi |
Answering the question
The Delhi pair are B (PO, rank 6) and G (Sub staff, rank 8). The question asks for the person who is the immediate junior of one Delhi person and the immediate senior of the other. Rank 7 sits between them: it is immediately below rank 6 and immediately above rank 8. Rank 7 is E (Clerk). So the required person is E.
Cross-check
Couples (B,D), (C,F), (A,G), (H,E) are each split across different cities; each city has equal males and females (Delhi B-G, Pune A-D-E-F, Hyderabad C-H); only C and H are in Hyderabad; the spouse of E (which is H) is not in Delhi. Every condition holds, so the arrangement is unique and E is confirmed.
