設concerntration為X, water為3X
4X=200 X=50
但所算出來的為6 ounce的can有50個, 所以如果為12 ounce的話則為50/2=25個
答案為選項(A)

但是怎麼從題目中知道算出來ㄉ50是6盎司的?

1 can of concentrate is to be mixed with 3 cans of water to make orange juice
一罐濃縮液跟3罐水混合成果汁
一罐果汁裡面的成分比是1 : 3
How many 12-ounce cans of the concentrate are required to prepare 200 6-ounce servings of orange juice
準備200瓶6盎司的果汁需要多少瓶12盎司的濃縮液
小弟是這樣解答的
果汁的總數是200(6) = 1200盎司
4x = 1200
x = 300
(果汁的成分比1:3..假設1份為x )
濃縮液的總數為300盎司
300 / 12 = 25

小弟的答案是A
