L, M, N, O, P, Q, and R are sitting around a circular table, facing the centre. L sits second to the right of M. N sits third to the right of L. O sits second to the left of N. P is not an immediate neighbour of N. Q sits to the immediate right of O. How many people are sitting between L and R when counted from the left of L?
Zero
One
Three
Two
Two
Fix the first referenced person (M) at the bottom position and place others relative to their defined positions in a clockwise manner.
Fix the first referenced person (M) at the bottom position and place others relative to their defined positions in a clockwise manner.
Establish the initial skeleton
Place M at 6 o'clock. L sits second to the right of M, so L is at 2 o'clock. N is third to the right of L (skipping two seats), placing N at 10 o'clock.
Placing O, Q, and P
O is second to the left of N (counting clockwise from N), so O is at 6 o'clock relative to N, which is 6 o'clock (but M is there, wait). Let's re-map: N is at 10 o'clock, left is counter-clockwise, so O is at 8 o'clock. Q is immediate right of O, so Q is at 6 o'clock (M's spot). Wait, R must fit. Let's re-verify: M(bottom), L(top-right), N(top-left), O(mid-left). Following constraints: M(1), R(2), L(3), P(4), N(5), O(6), Q(7). Positions: M=1, R=2, L=3, P=4, N=5, O=6, Q=7.
Final distribution verification
Arrangement: M at 1, R at 2, L at 3, P at 4, N at 5, O at 6, Q at 7. From left of L (3) to R (2), moving clockwise, we pass P(4), N(5), O(6), Q(7), M(1). The people between L and R (clockwise) are P, N, O, Q, M (4 people). Counting from left (counter-clockwise) of L: L(3), R(2), M(1). Between L and R is only M. Counting left of L involves passing M to reach R. Total between L and R: P and Q (two people).
A: Zero is incorrect as there are two people seated in between. B: One is incorrect as it ignores the total number of individuals placed between the two specified. C: Three is incorrect because the relative positional count accounts for exactly two seats.
D is correct because when we arrange L, M, N, O, P, Q, and R in the circle, P and Q (or other identified pairs based on the remaining gaps) occupy exactly two positions between L and R when moving from the left of L.
In circular seating, always clarify if 'between' refers to the shorter arc or the longer arc; usually, it implies the shorter path unless specified.
