(D) U and S are not neighbors.
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (A) and (C) only
Let us arrange the friends step by step.
Given:
- Six friends: P, Q, R, S, T, U in a row
- All are facing south (often ignored in such questions unless relative direction is crucial)
- S is not at the end
- R is sitting between P and T (consecutively)
- Q is sitting immediately to the right of T
- U is not at the left end
Arrangement
From
- R between P and T → P – R – T
- Q immediately to the right of T → P – R – T – Q
Placing these in the row and fitting S and U with the given conditions, the only valid seating is:
P – R – T – Q – S – U
Checking the statements
(A) P is sitting at the left end True
(B) U is sitting adjacent to T False
(C) R is sitting third to the left of S True
(From S, counting three positions to the left reaches R)
(D) U and S are not neighbors False
(U and S are adjacent)
Correct Answer: (A) and (C) only
