设k为整数,(399a+805)/(a+2)=k则:399a+805=ak+2ka*(399-k)=2k-805k=399时,以上等式不成立,所以:a=(2k-805)/(399-k)=-2-7/(3

由1：4x+4y=80x+y=20（3）由2：5x-5y=80x-y=16（4）（3）+（4）:2x=36x=18把x=18带入（4）：18-y=16y=2所以：x=18,y=2

=(399a+798+7)/(a+2)=(399a+798)/(a+2)+7/(a+2)=399+7/(a+2)是整数则7/(a+2)是整数a+2=1,-1,7,-7a=-1,-3,5,-9所以a=-

设甲原有钱x元,则乙原有钱为（805-x）元,可列方程：x+1/10*x=(805-x)+(805-x)/5则x=420因此,甲原有钱420元,乙原有钱385元.

甲有805/（1+1.1/1.2）=420元乙有805-420=385元110%甲是乙的120%倍
