Miki 有一打大小相同的橙子和一打大小相同的梨。Miki 用榨汁机从3个梨中榨出8盎司梨汁，从2个橙子中榨出8盎司橙汁。她用等数量的梨和橙子制作梨橙汁混合饮料。这个混合饮料中有百分之多少是梨汁？

(A) 30 30

(B) 40 40

(D) 60 60

(E) 70 70

Answer

Correct choice: (B)

正确答案：（B）

Solution

Use 6 pears to make 16 oz of pear juice and 6 oranges to make 24 oz of orange juice for a total of 40 oz of juice. The percent of pear juice is $\frac{16}{40} = \frac{4}{10} = 40\%$.

用6个梨制作16盎司梨汁，用6个橙子制作24盎司橙汁，总共40盎司汁。梨汁的百分比是 $\frac{16}{40} = \frac{4}{10} = 40\%$ 。
