Eight persons G, H, I, J, K, L, M and N are ranked at different designations, but not necessarily in the same order.
The order of designations is General Manager (GM), Deputy General Manager (DGM), Assistant General Manager (AGM), Manager, Probationary Officer (PO), Clerk, Analyst and Intern.
The person ranked as General Manager is considered as the seniormost, while the person ranked as Intern is considered as the juniormost person in the hierarchy.
Four persons are ranked between I and K. M is immediate junior to K. G is immediate senior to I.
| | Case 1 | Case 2 | Case 3 | Case 4 |
| Designation | Persons | Persons | Persons | Persons |
| General Manager (GM) | K | | | G |
| Deputy General Manager (DGM) | M | K | | I |
| Assistant General Manager (AGM) | | M | K | |
| Manager | | | M | |
| Probationary Officer (PO) | G | | | |
| Clerk | I | G | | |
| Analyst | | I | G | K |
| Intern | | | I | M |
The total number of persons junior to K is equal to the total number of persons senior to N.
Thus, case 2 and case 4 are invalid.
| | Case 1 | Case 3 |
| Designation | Persons | Persons |
| General Manager (GM) | K | |
| Deputy General Manager (DGM) | M | |
| Assistant General Manager (AGM) | | K |
| Manager | | M |
| Probationary Officer (PO) | G | |
| Clerk | I | N |
| Analyst | | G |
| Intern | N | I |
Two persons are ranked between H and J.
M is junior to J. Thus, case 1 is invalid.
| | Case 3 |
| Designation | Persons |
| General Manager (GM) | |
| Deputy General Manager (DGM) | J |
| Assistant General Manager (AGM) | K |
| Manager | M |
| Probationary Officer (PO) | H |
| Clerk | N |
| Analyst | G |
| Intern | I |
Therefore, the final arrangement is:
| Designation | Persons |
| General Manager (GM) | L |
| Deputy General Manager (DGM) | J |
| Assistant General Manager (AGM) | K |
| Manager | M |
| Probationary Officer (PO) | H |
| Clerk | N |
| Analyst | G |
| Intern | I |
L is immediate senior to J and is ranked as General Manager.
