Tina is 9 km North of Ravi; Mohan is 7 km West of Tina; Seema is 2 km South of Mohan. Where is Seema with respect to Ravi?

Step 1: Take Ravi as the fixed reference at (0,0). | Step 3: Continue on the same grid; the successive coordinates are Ravi=(0, 0), Tina=(0, 9), Mohan=(-7, 9), Seema=(-7, 7). | Step 4: For the requested relation, subtract Ravi's coordinates from Seema's coordinates: (-7,7) − (0,0) = (-7,7). | Step 5: The horizontal sign points West and the vertical sign points North. | Step 6: Together these signs give North-West; therefore Seema is North-West of Ravi. | Final Answer: Option D — North-West.
