Heuristic Math: Make a Systematic List

How would you interpret this question:

"Ricky opens a bank account with initial deposit of 2000 dollars. For every month, with maintaining balance of 5000 dollars or more, an interest of 2.5% will be added. An additional 1.2% for every 2000 dollars if exceeds to the maintaining balance. For the first 3 months, he maintained the required minimum balance to obtain the interest every month. The following months he deposited 1500 dollars every month. How many months required to have an outstanding balance of $18526?

*round off your answers to nearest one (truncate the decimal values)"

I've gotten the following answers:
10 Months - $18,458
9 Months - $19,456
10 Months - $18,756

Still, I think my answers are not correct. How do you guys understand the question and what is/are your answer/s?
