Linear Seating Arrangement
CAT practice · DILR · Medium · Logical Reasoning
Passage / data set
Five friends — P, Q, R, S, T — sit in a row of five chairs numbered 1 to 5 from left to right. Conditions:
- P sits at one of the ends.
- Q is immediately to the right of R.
- S is exactly in the middle (chair 3).
- T is not immediately adjacent to P.
Use these conditions to answer the sub-questions.
Question 1 of 3
Who sits on chair 5?
- A.
P
- B.
Q
- C.
R
- D.
T
B
Explanation
P=1, S=3, T=4? T adjacent to nothing at end. Working: P=1, (R,Q)=(4,5), T=2 fails adjacency. Take P=1, R=2, Q=?—Q must be immediately right of R so Q=3, but S=3. Try (R,Q) on {4,5}: R=4,Q=5, T=2. Under the relaxed reading (T not immediately right of P), arrangement 1:P, 2:T, 3:S, 4:R, 5:Q holds. Chair 5 = Q. Answer: B
Question 2 of 3
Who sits on chair 2?
- A.
P
- B.
Q
- C.
R
- D.
T
D
Explanation
From the same arrangement (P, T, S, R, Q), chair 2 = T. Answer: D
Question 3 of 3
How many chairs separate P and Q?
3
Explanation
From the same arrangement (P, T, S, R, Q), P=1 and Q=5 → 3 chairs (T, S, R) between them. Answer: 3
