Question

Five people L, M, N, O, and P sit in a row, not necessarily in the same order. P sits exactly in between M and N. If L sits exactly in between M and O, then which of the following must be true?

• A. O sits to the immediate right of M
• B. L and N always sit together
• C. M sits exactly at the middle of the row
• D. P sits between M and L

Answer 1

The Correct Option is C

Since P sits exactly between M and N, the arrangement is either M-P-N or N-P-M. Since L sits exactly between M and O, the arrangement for L and O must be M-L-O or O-L-M. From the above, M must be in the middle of the row, satisfying the condition that M sits exactly in the middle. In seating arrangement problems, always start by identifying fixed positions and then fit other conditions accordingly.
