Sixteen persons- A, B, C, D, E, F, G, H, I, J, K, L, M, N, O and P are sitting around the two concentric square tables- the inner table and the outer table. The inner table is surrounded by the outer table. Eight persons are sitting around each table such that four persons at the middle side of the table and four persons at the corner of the table. The persons at the inner table are facing outside the centre while the persons at the outer table are facing inside the centre. The persons sitting at the inner table are facing the persons sitting at the outer table.
Two persons sit between C and H.
C sits immediate right of O.
The vowel person does not sits at the corner of the table.


The one who sits opposite to H sits second to the left of E.
P is an immediate neighbor of E.
Neither P nor M sits opposite to C.
Three persons sit between P and M.


D sits second to the left of A.
A does not sits adjacent to M.
F sits adjacent to A but not adjacent to D.
Thus, Case 2 and Case 3 get cancelled.

Only one person sits between I and G.
I does not faces inside the centre.
I does not sits adjacent to M.
Thus, Case 4 gets cancelled.

B sits third to the left of N.

The one who faces J sits second to the left of Q.
M does not sits opposite to J.

Now, only K is remaining.

This is the final arrangement.

K sits fourth to the left of B.
