Six people E, H, K, M, S and U are seated in a circle facing the centre. U and H are immediate neighbours of M. E is the only person sitting between K and S. H is to the immediate right of S. Who is to the immediate right of U?

K

The correct answer is Option (3) → K

Now, ATQ,

i) U and H are immediate neighbours of M ⇒ means M is sitting between U & H

ii) E is the only person sitting between K and S.

iii) H is to the immediate right of S.

Now, lets make a circle and start sitting arrangement of the persons according to above situations. Key point is point number (iii). 

K is the immediate right of U.
