Six friends, J, K, L, M, N, and O, sit in a straight line facing north. N is fourth to the right of J. L is between M and N. K is not at an extreme. O is at the right end.
Who is second from the left end?
Show answer & explanation
Correct answer: D
Explanation
Let the six positions from left to right be numbered 1 to 6, all facing north:
• O is at the right end: Position 6 = O
• N is fourth to the right of J: Since position 6 is occupied by O, J must be at position 1 and N at position 5 (1 + 4 = 5).
• L is between M and N: Since N is at position 5, L must be at position 4 and M at position 3 (M – L – N).
• K is not at an extreme: The only remaining position is 2, so position 2 = K.
The complete arrangement from left to right is:
J — K — M — L — N — O
Therefore, K is second from the left end.
