Question

Eight persons sit in a row. Some face north, others face south. No more than two adjacent persons face the same direction. More than four persons sit between J and E, who faces north. M sits 2nd to the right of E. Four persons sit between K and G, and both face the same direction. R sits 2nd to the right of J. W sits 3rd to the right of G. R and P face the same direction. R and W are not adjacent.

Four of the following five belong to a group based on a certain property. Who does not belong to that group?

Accepted Answer

**Solution:**

1. From the given information, arrange the eight persons in a row:
   - E faces north.
   - More than four persons sit between J and E, so the distance between J and E is at least 5.
   - M sits 2nd to the right of E.
   - Four persons sit between K and G, and both face the same direction.
   - R sits 2nd to the right of J.
   - W sits 3rd to the right of G.
   - R and P face the same direction.
   - R and W are not adjacent.

2. Using these clues, the seating order is:
   E, K, M, W, P, R, G![image.png](https://res.cloudinary.com/aptidude/image/upload/v1758788147/aptidude_questions/w6ls9tgxqkgejl30cyeb.png), J

3. Directions:
   - E faces north.
   - K and G face the same direction.
   - R and P face the same direction.
   - No more than two adjacent persons face the same way.

4. Grouping:
   - R, K, G, and P all face the same direction (either north or south).
   - E faces north but does not share the same direction group as the others because of the seating and direction constraints.

5. Therefore, E does not belong to the group formed by R, K, G, and P.
