Seven boys, J, M, N, K, P, L and O, are sitting in a row facing North. K sits fifth to the left of J. K does not sit at either end of the row. L sits exactly in the middle of the row. L sits third to the right of M. Only two boys sit between O and P. O is not an immediate neighbour of L.
Who is sitting to the immediate right of L?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → N
All the boys face North, so their left and right are the same as ours. Number the seats 1 to 7 from the left and fix the boys whose seats are certain first.
L is exactly in the middle of seven seats, so L is in seat 4
L is third to the right of M, so M is in seat 4 − 3 = seat 1
K is fifth to the left of J, so K can be in seat 1 or 2 (with J in seat 6 or 7). Seat 1 is M’s and K is not at an end, so K is in seat 2 and J in seat 7
Seats 3, 5 and 6 are left for N, O and P. Only two boys sit between O and P, so O and P take seats 3 and 6
O is not next to L (seat 4), so O cannot be in seat 3: O is in seat 6 and P in seat 3
N takes the last seat, seat 5. The row is M, K, P, L, N, O, J
The boy to the immediate right of L (seat 5) is N
