Seven people, H, J, K, M, N, P and R, are sitting in a row, facing North. M sits at the extreme left end. P sits fourth to the right of M, and K sits to the immediate right of P. N sits second to the left of K. R sits neither at an end nor next to M. H sits somewhere to the left of J.
Who sits in the middle of the row?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → N
Facing North, left is the west end. Number the seats 1 to 7 from the left; the middle seat of seven is seat 4.
M is at the extreme left end: seat 1
P is fourth to the right of M: seat \(1+4=5\); K is to the immediate right of P: seat 6
N is second to the left of K: seat \(6-2=4\)
Seats 2, 3 and 7 are left. R is not at an end (not 7) and not next to M (not 2), so R is in seat 3
H is to the left of J, so H takes seat 2 and J seat 7. Order: M, H, R, N, P, K, J
The middle seat, 4, is N’s
