E, F, G and H are sitting in a straight line equidistant from each other (but not necessarily in the same order). Some of them are facing south, while some are facing north.
G sits second to the right of H, who faces north.
E is not an immediate neighbour of G and faces the same directions as G.
Both the immediate neighbours of H face the same direction.
G sits at one of the extreme ends of the line.
Both the immediate neighbours of F face the opposite directions.
How many persons in the given arrangement are facing south?

  • A.One
  • B.Three
  • C.Zero
  • D.Two

Answer: B

Three persons face south. G sits second to the right of H, who faces north and so has east on the right. G is at an extreme end, so H is second from the other end. E is not next to G, so E is at the far end and F is between H and G.

F's two neighbours, H and G, face opposite directions, so G faces south. E faces the same way as G, which is south. H's neighbours E and F face the same way, so F is south too. So E, F and G face south, and H faces north.
