If x +\( \frac{1}{x} \) = 3, then x⁶ + \( \frac{1}{x^6} \) is:
A certain number of advocates are sitting in a row in a bar council, facing north. Piyush is an immediate neighbour of both Vinod and Taman, while Rudir is an immediate neighbour of both Taman and Biswas. Vinod is sitting at the extreme right end.

An object is placed at a distance of 0.5 m in front of a converging mirror. If the focal length of the mirror is 0.2 m, then the magnification of the image is:
\( \frac{4}{3} \)
\( \frac{1}{3} \)
\( \frac{2}{3} \)
\( \frac{3}{2} \)
C, E, K, M, O, Q and Z are sitting around a round table facing towards the center (but not necessarily in the same order). C is the immediate neighbour of Z and M. O is neither an immediate neighbour of M nor E. Q, who is second to the left of O, has K and E as immediate neighbours.
Who is sitting to the immediate right of O?
