in a certain game played with red chips and blue chips, each red chip has a point value of X and each blue chip has a point value of Y, where X>Y and X and Y are positive integers. If a player has 5 red chips and 3 blue chips, what is the average (arithmetic mean ) point value of the 8 chips that the player has?

(1)   The average point value of one red chip and one blue chip is 5.

(2)   The average point value of the 8 chips that the player has is an integer.

The answer is C, how to analyze? Thank you.
