Question 1

Seven persons sit in a row facing north. Use the conditions: - Bhavya sits at the leftmost end. - Mira sits at the rightmost end. - If Bhavya sits to the left of Hina, then Wafa must be at an extreme end. - If Rhea is adjacent to Sahil, then Aarav does not sit at position 4. - Mira 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).
The first conditional is true and is consistent with the setup.
The second conditional helps constrain the positions of D, E, and F, leading to a unique solution.
Validated arrangement: Position 1: Bhavya; Position 2: Hina; Position 3: Wafa; Position 4: Rhea; Position 5: Sahil; Position 6: Aarav; Position 7: Mira
