Question 1

Seven persons sit in a row facing north. Use the conditions: - Eshan sits at the leftmost end. - Jatin sits at the rightmost end. - If Eshan sits to the left of Hina, then Nihal must be at an extreme end. - If Kaira is adjacent to Sahil, then Diya does not sit at position 4. - Jatin sits third from the left. Question: Who sits at position 4 from the left?
If-Then Conditional Strategy
Start with fixed endpoints and fixed position (third from left).
