Question

甲乙仓库比是4:3,把甲的三分之一给乙,则乙比甲多50吨,甲原有多少吨

Answer 1

如果把甲仓库原存货看成是1,那么乙仓库原存货是3/4
把甲仓库的1/3放入乙仓库中后,这时,甲仓库有1-1/3=2/3,乙仓库有3/4+1/3=13/12
12吨相当于甲仓库原存货的(13/12-2/3)
甲仓库原存货=120÷(13/12-2/3)
=50÷5/12
=50×12/5
=120吨
综合算式：
甲仓库原存货=50÷[(3/4+1/3)-(1-1/3)]
=50÷(13/12-2/3)
=50÷5/12
=50×12/5
=120吨

Answer 2

设：甲原有x吨则乙有3/4*x吨
x-1/3*x=3/4*x+1/3*x-50
2/3*x=13/12*x-50
13/12*x-2/3*x=50
5/13*x=50x=130吨
甲原有130吨

Answer 3

50÷[(3/4十l/3)-(l-1/3)]=120
