國家A的央行 資產負債表裡
資產項：政府債券2000 負債項：Currencies 1600 ,商業銀行的法定準備 400
它要問的是假設商業銀行不持有 Currencies ， 而法定準備率為20％
國家A的貨幣供給多少？
以上是題目的假設
書上解答是 1/0.2 乘（1600＋400） 答案是10000
但我的算法是 0.8＋1/0.8＋0.2 乘 （1600＋400） 算出來是3600
照書上的算法它擅自假設 C＝0 所以貨幣乘數是 1/R = 1/0.2 = 5
但題目裡面沒有這項假設，如果C＝0 後面貨幣基數（1600+400） 的1600哪來的？
麻煩各位了，快被這題搞瘋了，謝謝
