Equal number of people sit between L N and P-N

R and T are immediate neighbors of N

Three people sit between L and R

No of people sitting between T and L is two more than that between P and T.

R and T are immediate neighbors of N

RNT   or   TNR

Three people sit between Land R  , Equal number of people sit between L N and P-N

L   X  X  X  R  N   T  X  X  X  P    Case 1   or  P X X X  T N  R   X  X  X L

L   X   T  N  R  X   P                     Case 2  or   P  X   R  N  T  X   L
