Answer:
$900
Step-by-step explanation:
As $1,000 is deposited in the account by Mr. Y in the Bank A. But the further requirement of the reserve is 0.10. So, it will amounts to:
Amount of reserve requirement = Amount deposited × Requirement of reserve
where
Amount deposited is $1,000
Requirement of reserve is 0.10
= $1,000 × 0.10
= $100
Therefore, the initial amount of the money that created by excess reserve is:
= Amount deposited - Amount of reserve requirement
= $1,000 - $100
= $900
