Question 1

Seven persons sit in a row facing north. Use the conditions: - Hina sits at the leftmost end. - Jatin sits at the rightmost end. - If Hina sits to the left of Mira, then Omar must be at an extreme end. - If Zoya is adjacent to Wafa, then Fatima 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).
