Question 1

Seven persons sit in a row facing north. Use the conditions: - Xavier sits at the leftmost end. - Diya sits at the rightmost end. - If Xavier sits to the left of Tara, then Cyrus must be at an extreme end. - If Jatin is adjacent to Fatima, then Priya does not sit at position 4. - Diya 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).
