Eight friends - S, T, U, V, W, X, Y and Z are sitting around a square table facing the centre. They sit in such a way that four of them sit at four corners of the square while four sit in the middle of each of the four sides. Only Z sits between S and X. S sits in the middle of one of the sides. V sits third to the right of X. Both Y and Z are immediate neighbours of S. T sits second to left of U. Who sits third to the left of X?

Eight friends - S, T, U, V, W, X, Y and Z are sitting around a square table facing the centre. They sit in such a way that four of them sit at four corners of the square while four sit in the middle of each of the four sides. 

Only Z sits between S and X.

S sits in the middle of one of the sides.

V sits third to the right of X.

Both Y and Z are immediate neighbours of S. 

T sits second to left of U

So, Y sits third to the left of X.

Thus, the correct option is: (c)
