- AOne student
- BFour students
- CTwo students
- DThree students
Solution & Step-by-step Explanation
1. There are 4 seats: [_ _ _ *].
2. G and K are at extreme ends.
3. J is 3rd from the right end. In a 4-seat row, 3rd from right is the 2nd seat from the left.
Row: [* J _ _]
4. Since G is at an end, G must be at the left end (1st seat).
Row: [G J _ _]
5. Since K is at an end, K must be at the right end (4th seat).
Row: [G J _ K]
6. H is to the immediate left of K. That is the 3rd seat.
Final Row: [G J H K]
7. Students between G and H: Only J is sitting between them.
Number of students = 1.
