Directions (91-95): Study the following information carefully and answer the questions given below:

Seven persons ( A-G) work in the same organization on seven different designations (MD, CEO, SR. MGR, MGR, PO, Clerk and Typist ) but not necessarily in the same order. The designations are in the decreasing order such that MD is the senior-most position and Typist is the junior-most position.

The numbers of persons senior to A is same as the numbers of persons junior to A. B is junior to A and just senior to C. E is junior to A. The numbers of persons junior to C is same as the numbers of persons designated between B and D. At most one person between G and F. F is not the senior most.

Which designation does F hold in the organization?

To determine the designation that F holds, we can systematically analyze the given clues step-by-step.

First, let us list the designations in decreasing order of seniority:
1. MD (Senior-most)
2. CEO
3. SR. MGR
4. MGR
5. PO
6. Clerk
7. Typist (Junior-most)

Step 1: Determine the position of A
The clue states that "The number of persons senior to A is same as the number of persons junior to A."
Since there are 7 designations in total, the middle position is the 4th position. Therefore, A must be the MGR.

Step 2: Determine the positions of B, C, and E
We are told that "B is junior to A and just senior to C" and "E is junior to A."
Since A is at position 4 (MGR), the positions junior to A are 5 (PO), 6 (Clerk), and 7 (Typist). Since B is just senior to C, they must occupy consecutive positions. This gives us two possible cases:
• Case 1: B is PO (5) and C is Clerk (6). In this case, the only remaining junior position for E is Typist (7).
• Case 2: B is Clerk (6) and C is Typist (7). In this case, the only remaining junior position for E is PO (5).

Step 3: Apply the condition about C, B, and D
The clue states: "The number of persons junior to C is same as the number of persons designated between B and D."
Let us evaluate both cases:
• In Case 2, C is Typist (7), which means there are 0 persons junior to C. This requires 0 persons between B (Clerk, 6) and D, meaning D must be adjacent to B (either position 5 or 7). However, position 7 is occupied by C, and position 5 is occupied by E. Therefore, Case 2 is invalid.
• In Case 1, C is Clerk (6), which means there is exactly 1 person junior to C (E at position 7). Therefore, there must be exactly 1 person between B (PO, 5) and D. This places D at position 3 (SR. MGR), with A (MGR, 4) being the single person between them. This case is valid.

At this stage, the arrangement is:
1. MD: [Vacant]
2. CEO: [Vacant]
3. SR. MGR: D
4. MGR: A
5. PO: B
6. Clerk: C
7. Typist: E

Step 4: Place G and F
The remaining vacant positions are MD (1) and CEO (2) for the remaining persons G and F.
We are told that "At most one person between G and F" (which is satisfied as they are adjacent) and "F is not the senior-most."
Since F cannot be the senior-most (MD), F must be the CEO and G must be the MD.

Final Arrangement:
1. MD - G
2. CEO - F
3. SR. MGR - D
4. MGR - A
5. PO - B
6. Clerk - C
7. Typist - E

Therefore, F holds the designation of CEO. Since CEO is not listed in the options (Clerk, Typist, PO, MGR), the correct option is None of these.
