O, P, Q, R, S and T are sitting around a circular table facing the centre. P sits second to the left of T. Q is the immediate neighbour of P and R. S is not the immediate neighbour of R. Who sits to the immediate left of R?

O
Place T at the bottom, then place P to its second left. Since Q neighbors P and R, place them in a sequence. Use the constraint about S to fix the remaining positions.
Place T at the bottom, then place P to its second left. Since Q neighbors P and R, place them in a sequence. Use the constraint about S to fix the remaining positions.
Establish Reference
Place T at the bottom of the circle. P is second to the left of T, placing P at the 10 o'clock position.
Fix Neighbors of P
Q is an immediate neighbor of P and R. Since P is at 10 o'clock, Q must be at 8 o'clock and R at 6 o'clock (moving clockwise).
Constraint Verification
S is not a neighbor of R. Available spots are 2 o'clock and 4 o'clock. S must go to 2 o'clock to avoid being next to R. This leaves O for the 4 o'clock position.
Determine Position
In a clockwise sequence T(12), S(2), O(4), R(6), Q(8), P(10). The person to the immediate left of R (at 6 o'clock) is O (at 4 o'clock).
A: S sits to the immediate right of T, not left of R. B: Q is the immediate neighbor of P and R, not left of R. D: T sits opposite R.
C is correct because placing the members according to the constraints results in O occupying the seat to the immediate left of R.
In circular seating puzzles, always fix the person mentioned in the primary constraint first, then build the sequence based on 'immediate neighbor' rules.
