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

hmm. why not E? from A, it says-(r+b)/2=5 hence r+b=10. from B we therefore have- [b+b+(r+b)+(r+b)+(r+b)]/8= some integer. both A and B, 2b+30/8 = some integer. hence when b= 1, avg= 4 b=9, avg = 6. . so i think E.

(x+y)/2=5 --> x+y=10

1: But we cannot deduce what x and y are . Insuff.

2: (5x+3y)/8= integer... Again could be anything.

Together:

Try numbers: note that X>Y. So we can try 6,4. 7,3, 8,2 and 9, 1.
