Econ問題 - Banking system

請問搵Maximum possible amount of loan 有冇formula背??
仲有total money supply點計??
另外有條econ問題知答案但唔識解~請各位幫下忙解佐佢:
The table below shows the balace sheet of a banking system, which has an excess reserves of $50.
Assets:
Reserves $250
Loans:$750
Liabilities:
Deposits $1000
個答案寫:If $100 withdrawn from the banking system, the maximum possible total deposits will be $750.
但係maximum possible total deposits 唔係應該: -100*(1000/200)+1000=$1000咩??
請識ge人幫幫忙!!

✔ 最佳答案

maximum possible amount of loan = reserves/minimum reserve ratio - reserves 我諗咁樣計會好D
total money supply = cash hold by public + deposits

佢話有50蚊係excess
姐係minimum reserves ratio = (250-50)/1000 = 0.2
咁有100蚊比人提走左
姐係reserves就得返150蚊
所以maximum possible total deposits
= reserves/minimum reserves ratio
= 150/0.2 = 750
