Earlier average of a game played is 869. You played 10 games and the current average is 855. What is your 10 game average?

864.6 provided the game was only played once before the 10 recent games. If thats true, then it easy. Do this:
(869 + 10x)/11 = 865

If there were more than 1 game played then we have insufficient information.

This would make for a good DS question or a deadly PS question if the answer choices included 864.6 & None of the above.
