Answer:
$1200
Explanation:
Since the type of account isn't specified, we assume you deposit the money in a current account. When you deposit in such an account, you receive no interest. Also, assuming that you don't make additional deposit and don't withdraw, the balance will remain as it was. Lastly, we assume that when you made the deposit, the account balance was initially zero. Therefore, there will be no change in your account balance after 3 months.
