Six persons, K, M, O, R, S and T, are standing in a row, facing North. M is at the right end of the row. K is second to the left of M, and S stands between K and M. T is second to the left of K. R and T are immediate neighbours. O is to the right of T.
Who is fourth to the left of M?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → T
Facing North, a person’s right is the right side of the row. Number the places 1 to 6 from the left and start from the person at the end.
M is at the right end: place 6. K is second to the left of M: place 4, and S, between them, is in place 5
T is second to the left of K: place 2
R is next to T, so R is in place 1 or 3; O is to the right of T, and the only free place to the right of T is place 3
So O is in place 3 and R in place 1
The row is R, T, O, K, S, M. Fourth to the left of M (place 6 − 4 = place 2) is T
