Answer:
required reserved $1000
loan that bank can offer $3000
excessive reserve on the deposit $ 2000
Step-by-step explanation:
the required reserved can be obtained by suing following relation
required reserved = customer deposits * reserve ration
= 4000*0.25 = $1000
the largest loan that bank can offer will be = 4000 - 1000 = $3000
if the bank hold $3000, the excessive reserve on the deposit = 3000 - 1000 =$ 2000
