A, B and C just finished their breakfast. One of the boys had apples, another bananas and the third, grapes. If only one of the following four statements is true, who had what for breakfast?

C had bananas.

C did not have grapes.

B did not have grapes.

B did not have apples.

One of the statements is true, and its not possible for statements 3 and 4 to both be false, so one is true.

That means statements 1 & 2 are both false, so C had grapes.

That means statement 3 is true, and statement 4 is false, so B had apples.

That leaves A, who had bananas.
