A: 1800
A1: 540
Trip2:
From A to A1, horse takes 900 bananas.
Eats 360 and is back at A.
A: 900
A1: 1080
Trip3:

Eats 180 and is at A1.
A1: 1080+720 = 1800
Trip4:

Eats 600 and is back at A1
A1: 900
A2: 300
Trip5:

Eats 300 and is at A2
A2: 900
Trip6:

B: 900-420 = 480
Distance between A and B is : 900km
Horse can take 900 Bananas at a time and it can it 1 banana after every 1 km so horse can eat 900 bananas after reaching point B in the first trip. Like wise in all the three trips horse can eat all the 2700 bananas..so answer is zero..
@Kiran:
When your horse did 1st trip - it took 900 bananas from A and reached B with zero stock. How will it return now without bananas ?
