Show answer & explanation
Correct answer: A
Solution: place people step by step and determine who is third to the right of P.
Number the seven seats clockwise from 0 to 6 and place R at seat 0 as a reference.
S is third to the right of R, so S is at seat 3 (move three seats clockwise from R).
S is also second to the left of V. That means V is two seats clockwise from S, so V is at seat 5.
Seats now occupied: R at 0, S at 3, V at 5. Remaining seats are 1, 2, 4, 6.
T and U are not immediate neighbours of R, so they cannot be at seats 6 or 1 (the seats next to R). Therefore T and U must occupy seats 2 and 4.
P is second to the right of T. If T were at seat 2, P would be at seat 4, but that would conflict with U occupying seat 4. So T must be at seat 4 and U at seat 2. Then P (second to the right of T) is at seat 6.
Third to the right of P (move three seats clockwise from seat 6) is seat 2, which is occupied by U.
Answer: U is sitting third to the right of P.
