Show answer & explanation
Correct answer: C
Answer: Either statement alone is sufficient.
Explanation:
From the first statement: R is third to the left of Q and P is second to the right of R. In a line of five this gives arrangements such as R, _, P, Q, _ or _, R, _, P, Q. In every valid placement the person immediately to the right of P is Q.
From the second statement: Q is immediately left of T, and T is second to the right of P. These conditions force the trio to appear as P, Q, T in that order, so the person immediately to the right of P is Q.
Conclusion: Each statement alone fixes the person immediately to the right of P as Q; therefore either statement alone is sufficient.
