Eight persons sit in a linear row and face north. All of them work in a company on different designations viz. CMD, CEO, COO, CFO, Manager, AM, HR and Intern.

S sits third to the right of P who is CMD, and either of them sit on the extreme end of the row. Two persons sit between S and the one who is Intern. T is an immediate neighbor of S and sits third to the left of V. Four persons sit between V and U who is COO. The number of persons sit left of R is same as the number of persons sit right of W. R is not intern. The one who is AM sits second left of Q who is CFO. The one who is CEO sits left of the one who is Manager but sits right of the one who is HR.

Who among the following is HR of the company?

The correct option is R.

Step-by-step Explanation:

Let us analyze the given conditions step-by-step to arrange the 8 persons and their respective designations in a linear row facing north (positions 1 to 8 from left to right).

1. Positions of P and S:
S sits third to the right of P (CMD), and either of them sits at an extreme end.
Since S is to the right of P, S can be at position 8 or P can be at position 1.
- If P is at position 1 (Left end): S sits third to the right of P, so S is at position 4. (P = 1st, S = 4th).
- If S is at position 8 (Right end): P sits third to the left of S, so P is at position 5. (P = 5th, S = 8th).

2. Positions of T, V, and U:
T is an immediate neighbor of S and sits third to the left of V.
Four persons sit between V and U, where U is COO.
Let us evaluate the cases:
Case 1: P at position 1, S at position 4.
- If T is at position 3: T sits third to the left of V, so V is at position 6. Then 4 persons sit between V (6th) and U (1st), but P is already at position 1. So T cannot be at position 3.
- If T is at position 5: V sits third to the right of T, so V is at position 8. Then 4 persons sit between V (8th) and U, placing U at position 3. (U = COO at 3rd position).
This gives: P(1), _(2), U(3), S(4), T(5), _(6), _(7), V(8).

3. Position of Intern:
Two persons sit between S and the Intern.
S is at position 4. Two persons between S and Intern means Intern can be at position 1 or 7.
Since P (CMD) is at position 1, the Intern must be at position 7.

4. Positions of R and W:
The number of persons sitting to the left of R is equal to the number of persons sitting to the right of W.
R is not the Intern (so R cannot be at position 7).
The available positions for persons are 2, 6, and 7.
Since R cannot be at position 7, if R is at position 2 (1 person to the left of R), then W must be at position 7 (1 person to the right of W).
The remaining position 6 goes to Q (who is CFO).
So the seating arrangement of persons from left to right (1 to 8) is:
1: P (CMD)
2: R
3: U (COO)
4: S
5: T
6: Q (CFO)
7: W (Intern)
8: V

5. Designations:
- Q is CFO.
- The one who is AM sits second to the left of Q (6th position), so the AM is at position 4 (S = AM).
- The remaining designations to place are HR, CEO, and Manager.
- We are given: CEO sits left of Manager but right of HR.
- The remaining positions without designations are 2 (R), 5 (T), and 8 (V).
- Ordering them from left to right (2, 5, 8):
- Position 2 (R) = HR
- Position 5 (T) = CEO
- Position 8 (V) = Manager

Thus, R is the HR of the company.
