Direction: The figure (not drawn on scale) given below shows the aerial distance (in km) between 8 cities, e.g. distance between H and F is 600 km etc.

-
What is the minimum distance between H to A through D?
-
- 1800
- 2000
- 2200
- None of these
Correct Option: D
On the basis of above given diagram , we can say that
The minimum distance between A and H through D is HEDCA and distance is 500 + 500 + 500 + 600 = 2100.
Hence , required answer will be 2100 km.
