Because the last three people ate the same number of oranges, each person had 16 oranges. C pondered, and finally gave A and B some oranges, knowing that A and B both had 8 oranges, while C had 32 oranges. Then it is inferred that B has four oranges for A and 16 oranges for C, so before B takes oranges, B has 28 oranges, C has 16 oranges and A has them.
