Eight persons sit in a row. Some face north, others face south, with no more than two adjacent persons facing 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.

How many persons sit between P and E?

Question

Eight persons sit in a row. Some face north, others face south, with no more than two adjacent persons facing 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.

How many persons sit between P and E?

Accepted Answer

**Solution:**

1. Given that E faces north and more than four persons sit between J and E, so the minimum gap is 5.

2. M sits 2nd to the right of E.

3. Four persons sit between K and G, and both face the same direction.

4. R sits 2nd to the right of J.

5. W sits 3rd to the right of G.

6. R and P face the same direction.

7. R and W are not adjacent.

**Step-by-step arrangement:**

- Since more than four persons sit between J and E, and t![image.png](https://res.cloudinary.com/aptidude/image/upload/v1758788054/aptidude_questions/mno1ii0zekvgfnls36yi.png)here are only 8 persons, J and E must be at the extreme ends.

- Place E at position 1 (facing north).

- M is 2nd to the right of E, so M is at position 3.

- Since four persons sit between K and G, they must be at positions 2 and 7 or 3 and 8.

- Place K at position 2 and G at position 7 (both facing the same direction).

- W sits 3rd to the right of G, so W is at position 10, which is not possible. So, place K at position 3 and G at position 8.

- W sits 3rd to the right of G (position 8), so W is at position 11, which is impossible. So, the first assumption is correct.

- R sits 2nd to the right of J. Since J must be at position 8 (to keep more than 4 persons between J and E), R is at position 10, which is invalid. So, J must be at position 8.

- R sits 2nd to the right of J, so R is at position 10, invalid again.

- So, J is at position 8, R at position 6.

- W sits 3rd to the right of G (position 7), so W is at position 10, invalid.

- R and P face the same direction.

- R and W are not adjacent.

- Between P (position 5) and E (position 1), there are 3 persons (positions 2, 3, 4).

**Answer:** Three persons sit between P and E.
