[問題] GWD math 24-3
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.
此題答案是C還是E呢? 自己覺得是E 因為題目有給出X>Y
這樣第二的條件 5X+3Y/8 怎麼配得出整數
煩請高手解答
