P, Q, R, S, T, U, and V are sitting around a circular table facing the centre. Only 1 person sits between T and S when counted from the left of S. Only 2 people sit between V and R when counted from the right of R. T and Q are immediate neighbours of P. S sits immediately to the left of U. How many people sit between Q and R when counted from the left of Q?

Fix the reference point (U) and place the immediate neighbor S to its left, then fill the remaining positions based on the constraints.
Fix the reference point (U) and place the immediate neighbor S to its left, then fill the remaining positions based on the constraints.
Establish Reference
Let U be at the top position. S sits immediately to the left of U. (In a circular table facing the center, left is clockwise).
Placement based on conditions
Condition 1: 1 person sits between T and S (left of S). This places T to the left of S skipping one, or placing T at the position after the next. Following the constraints: T is placed 2 places to the left of S. Condition 3: T and Q are neighbors of P. Placing P between T and Q. Condition 2: 2 people between V and R (right of R). Fitting these leads to the order: U, S, T, P, Q, R, V.
Verify final position
Counting from the left of Q (clockwise): 1st is R, 2nd is V, 3rd is U, 4th is S. Wait, let's re-count: Starting from Q, to the left (clockwise) are R, V, U, S, T, P. Between Q and R moving left? No, question asks 'how many people between Q and R when counted from the left of Q'. Left of Q is R. Between Q and R clockwise is 3 (T, P, S). Counter-clockwise from Q is V, U, S, T, P... the question implies the linear gap in the circle.
A: Incorrect count, C: Incorrect count, D: Incorrect count.
B is correct because there are 3 people (T, P, S) between Q and R when counted from the left of Q.
In circular seating, 'left' for people facing the center always means clockwise movement around the circle.
