Answer: Increases; remains unchanged
Explanation:
Given that,
A person withdraws from saving account = $500
M1 consists of:
M1 = Currency with public + checking account + other deposits with RBI
M2 consists of:
M2 = M1 + post office savings account deposits
A person withdraws from his savings account, as a result M2 will fall and then put this amount in his checking account which increases M1. We know that M1 is a component of M2, hence, M2 also increases.
Therefore, there will be no change occur in M2 and M1 increases.
