Mr A & Mr B Bank Loan

[touchthescreen]

So, Mr A & Mr B has taken out a bank loan on their shared account.

The loan is of 15,000 and is to be paid back in 60 months (5 years).

With interest it will amount to 16,500 in 5 years.

However, they divided the money unevenly between them;
Mr A: 6,300
Mr B: 8,700

Their joint monthly payment is 275.

How much should they pay each per month?

I'm assuming that the goal of the problem is to find payments for Mr A and Mr B such that they each pay an amount proportional to the amount they borrowed. What percentage of the initial loan amount did Mr A borrow? And then how much is that same percentage of their combined monthly payment?
