: There were 2 apples and 5 bananas in a basket. After additional
: apples and bananas were placed in the basket, the ration of the
: number of bananas was 1/2. How many apples were added?
: (1) The number of apples added was 2/3 the number of bananas added.
: (2) A total of 5 apples and bananas were added.
Xa=APPLE 增加量 Xb=bananas 增加量
2+xa=5+xb
xa=xb+3
若 xa=4 則xb=1 xa+xb=5
所以答案選D
