Question

Four baskets contain 1, 4, 6, and 9 apples respectively. At least how many apples should be moved between the baskets to have the same number of apples in each basket?

Answer 1

Mmmm tricky but I'll try..

take away 4 apples from the basket with 9 and place it in the one with 1 apple

then take away one apple from the one with 6 and place it in the basket with 4

And now you have 5 apples in each basket

Happy now?
