Question

Nine persons are seated in a straight line. Three of them face south, and the remaining face north. No more than two persons sitting next to each other face the same direction. Six persons sit between H and P, who is the only neighbor of R. G sits 3rd to the right of W, and W sits 2nd to the right of H. The number of persons to the right of G is fewer than those to the left of G. U and L sit immediately next to each other, with U to the left of L. O sits 2nd to the right of L and faces the same direction as W. J sits to the right of O.

How many persons sit between J and L?

Accepted Answer

**Solution:**

1. Given that there are 9 persons sitting in a row with some facing north and some south, and no more than two adjacent persons face the same direction.

2. Six persons sit between H and P, and P is the only neighbor of R. This means R and P sit next to each other.

3. W sits 2nd to the right of H, and G sits 3rd to the right of W.

4. The number of persons to the right of G is less than those to the left, so G is closer to the right end.

5. U and L sit immediately next to each other, with U to the left of L.

6. O sits 2nd to the right of L and faces the same direction as W.

7. J sits to the right of O.

By arranging the persons according to these clues, the order from left to right is:

H - J - W - U - L - G - O - P - R

Counting the number of persons between J and L:

- J is at position 2
- L is at position 5

Persons between J and L are at positions 3 and 4 (W and U), so there are 2 persons between J and L.
