​

Answer 1

Answer:

Step-by-step explanation:

The correct answer is 400 oranges.

A total of 640 oranges are in both the baskets. So, if 1/5th of the oranges are removed from the first basket and put into the second basket, that means at least 4/5th should remain in the 1st basket. But the question says that there were oranges already in the second basket also. So the nearest option is 400 oranges.
