He can carry maximum of only 1000 bananas at a time and eats 1 banana after he travels 1km distance. find the maximum number of bananas that he finally caries to the destination (city B).

OK now that's funny! Suppose he starts with 1000 bananas, and eats one banana after every one km. when reached 1000 kms, he is left with none. How will he come back to take other 2000 bananas (coz he is left with no more bananas)?

PS: If it sounds too silly, ignore it.

If the elephant carries 1000 bananas at a time, how can he take remaining 2000 bananas with him?

@farjand, varsha0802- please apply a bit of your brains.............. there is nothing wrong with the question.....
it's not specified that the elephant travels 1000 km at once........
let he travels only 400 kms, drops 200 banana's there, comes back with remaining 400 bananas, repeats the procedure.......
and at last reaches the destination with 400 bananas............. correct me if i m wrong......

Oh ok I got it now. I thought he has to travel whole distance at once. 400 is the correct answer. And ya, I never said there was anything wrong with the question.

In the first 200 kilometers, the elephant eats 1,000 bananas (5 bananas per kilometer). In the next 333 kilometers, the elephant eats 1,000 bananas approximately (3 bananas per kilometer). In the next 467 kilometer, the elephant eats 467 bananas (only 1 banana per kilometer). So, there will be 533 bananas in the end.

The distance between point A and point B is 1,000 kilometers. After travelling 1 kilometer from point A, you ask the elephant to unload 998 bananas and go back to point A. The elephant carries 1 banana with him to point A (that 1 banana will be eaten by the elephant after reaching point A). You will then ask the elephant to carry 1,000 bananas (the second set). After travelling 1 kilometer from point A, you ask the elephant to unload 998 bananas and go back to point A. The elephant carries 1 banana with him to point A (that 1 banana will be eaten by the elephant after reaching point A). You will then ask the elephant to carry 1,000 bananas (the third set). After travelling 1 kilometer from point A, you ask the elephant to unload 999 bananas. So, at this point you have 2,995 bananas at 1 kilometer from point A. In other words, the rate of banana consumption is 5 bananas per kilometer. You repeat this process until you reach point B. The rate of consumption decreases to 3 bananas per kilometer (after 200 kilometers). The rate of consumption decreases to 1 banana per kilometer (after 533 kilometers).

Hope this is clear to you now.
