Six people J, K, L, M, N and O sit in a row facing north. K sits at one of the ends. L sits third to the right of K. M sits immediately to the left of L, and O immediately to the right of L. N does not sit next to K. How many people sit between K and O?
Correct answer: C. Three
L is third to the right of K, so K cannot be at the right end: K is 1st and L is 4th. Then M is 3rd and O is 5th. Places 2 and 6 remain; N cannot sit next to K, so N is 6th and J is 2nd. Order: K J M L O N.
