有甲、乙两筐苹果,如果从甲筐取12个放入乙筐,则甲筐苹果个数是乙筐的1.2倍,已知甲筐原来比乙筐多50个苹甲筐原来有苹果多少个?
网友回答
设甲X个,乙X-50个
X-12 = 1.2*(X-50+12)
X-12 = 1.2*(X-38)
X-12 = 1.2X-45.6
45.6-12 = 1.2X-X
33.6 = 0.2X
0.2X = 33.6
X = 33.6/0.2
X = 168 甲有168个
======以下答案可供参考======
供参考答案1:
设甲框x个x-12=1.2*（x-50+12）
解得x=168供参考答案2:
设甲框为x个，乙为y个，根据题意得到
x-y=50
（x-12）/（y+12）=1.2
