Question

Six people, D, E, F, G, H and I, are sitting in a row, facing towards the north. H is sitting to the immediate right of F and to the immediate left of D. E is sitting to the right of F and three people are sitting in between them. G is sitting to the immediate left of E. I is sitting to the immediate right of E. Three of the following four are alike in a certain way based on the given arrangement and thus form a group. Which is the one that DOES NOT belong to that group?

The correct answer is

HE

To solve this problem, we need to understand the seating arrangement of the six people: D, E, F, G, H, and I. Let's break down the information given and arrange them accordingly:

  1. Everyone is sitting in a single row facing towards the north.
  2. From the clue, "H is sitting to the immediate right of F and to the immediate left of D", we can depict this as: F - H - D
  3. E is to the right of F and there are three people between them. So, the arrangement becomes: F - H - D - \_ - \_ - \_ - E
  4. G is sitting to the immediate left of E, which gives us: G - E. Integrating with the previous arrangement: F - H - D - G - E. (However, there seems to be an error as G can't sit to the immediate left with this layout, so we'll adjust accordingly in subsequent steps.)
  5. Finally, I is sitting to the immediate right of E. This helps us finalize the arrangement: F - H - D - G - E - I

Now, let's confirm the complete correct seating order:

  1. The final sequence should be: F - H - D - G - E - I, with everyone appropriately placed according to given positions and rules.

Next, let's evaluate the relationships between them to solve the last part of the problem.

  • HE: Neither H nor E are seated next to each other.
  • EI: E and I are immediate neighbors.
  • FH: F and H are immediate neighbors.
  • DG: D and G are immediate neighbors.

Considering the seating arrangement, connections such as EI, FH, and DG involve immediate neighbors. However, HE does not exhibit this characteristic as they are not adjacent.

Thus, the option that does not belong to the group is HE.
