There are 3000 bananas and an elephant has responsibility to carry these bananas from one city " Bangalore" to other city "New Delhi". Distance between bangalore to new delhi is 1000 Km . The elephant eat one bananas to run/walk 1 km else he can't walk/run for one step also. The elephant can carry 1000 banas only in a while, this is limit of elephant.

So can you tell me guys how much maximum number of bananas the Elephant succesfully can delivere to city New delhi ?

Note: Elephant is human being so he can do as continuos Function Means 1/2 bananas 1/2 km,1/4 bananas 1/4 Km.
