Directions: Read the following information carefully and answer the question given below.
Seven project managers—J, K, L, M, N, P, and Q—sit in a single row facing north. Each manager oversees a different domain: Edtech, Cleantech, Fintech, Biotech, Robotics, Agritech, and Aerospace, though not necessarily in that order.
The manager overseeing Biotech sits fourth from the left end of the row. M oversees Biotech. Two managers sit between M and J, with J sitting to the left of M. J oversees Edtech. The manager overseeing Cleantech sits to the immediate right of J. K sits to the immediate left of L, who oversees Fintech. Q sits at the extreme right end of the row and oversees Aerospace. The manager overseeing Robotics sits second to the left of Q. N sits somewhere to the right of P.
Which of the following projects is managed by N?
Correct Answer :
Agritech
Solution :
The correct answer is Agritech.
Step-by-step Explanation:
There are 7 managers (J, K, L, M, N, P, and Q) sitting in a row facing north. Let the positions from left to right be numbered 1 to 7.
Step 1: Place M, J, Q, and their known domains.
1. "The manager overseeing Biotech sits 4th from the left end of the row. M oversees Biotech."
⇒ Position 4 = M (Biotech)
2. "Two managers sit between M and J, with J sitting to the left of M. J oversees Edtech."
Since M is at Position 4, placing 2 managers to the left of M puts J at Position 1.
⇒ Position 1 = J (Edtech)
3. "The manager overseeing Cleantech sits to the immediate right of J."
⇒ Position 2 (Domain) = Cleantech
4. "Q sits at the extreme right end of the row and oversees Aerospace."
⇒ Position 7 = Q (Aerospace)
5. "The manager overseeing Robotics sits second to the left of Q."
Second to the left of Position 7 is Position 5.
⇒ Position 5 (Domain) = Robotics
Step 2: Place K and L.
We are told that "K sits to the immediate left of L, who oversees Fintech." This means K and L must occupy two consecutive positions (K at position n, L at position n+1 with Fintech).
Currently, our arrangement looks like:
- Position 1: J (Edtech)
- Position 2: [Manager?] (Cleantech)
- Position 3: [Manager?] [Domain?]
- Position 4: M (Biotech)
- Position 5: [Manager?] (Robotics)
- Position 6: [Manager?] [Domain?]
- Position 7: Q (Aerospace)
The only consecutive pair of positions where L can oversee Fintech is Position 2 and Position 3.
⇒ Position 2 = K (Cleantech)
⇒ Position 3 = L (Fintech)
Step 3: Place P and N, and assign the remaining domain to N.
The remaining unoccupied positions for managers are Position 5 and Position 6. We are given that "N sits somewhere to the right of P."
⇒ Position 5 = P (Robotics)
⇒ Position 6 = N
Now, summarizing the entire arrangement:
- Position 1: J — Edtech
- Position 2: K — Cleantech
- Position 3: L — Fintech
- Position 4: M — Biotech
- Position 5: P — Robotics
- Position 6: N — Agritech (the only remaining domain)
- Position 7: Q — Aerospace
Therefore, the project managed by N is Agritech.
