你好,同学。 方案一,总的净现金流入100*75%*(P/F,10%,1)%2B100*75%*(P/F,10%,2)%2B100*75%*(P/F,10%,3) 方案二,总的净现金流入50*75%*(P/F,10%,1)%2B100*75%*(P/F,10%,2)%2B150*75%*(P/F,10%,3) 方案三,总的净现金流入50*75%*(P/F,10%,1)%2B50*75%*(P/F,10%,2)%2B200*75%*(P/F,10%,3) 方案一,总的净现金流入100*(P/F,10%,1)%2B100*(P/F,10%,2)%2B100*75%*(P/F,10%,3) 方案二,总的净现金流入50*(P/F,10%,1)%2B100*(P/F,10%,2)%2B150*75%*(P/F,10%,3) 方案三,总的净现金流入50*(P/F,10%,1)%2B50*(P/F,10%,2)%2B200*75%*(P/F,10%,3) 你查系数表计算一下结果,结果大的方案好。
