Mr. San Jose owes Mr. Barro the following obligations:

1. Php 10 000 due in 3 years from today with accumulated interest at 10% converted quarterly;

2. Php 12 750 due at the end of 4 years with 5% simple interest rate; and

3. Php 19 400 due at the end of 5 years with accumulated interest at 9% compounded monthly;

If Mr. Barro specifies that money is worth 12% compounded monthly, what single payment at the end of 3 years will settle Mr. San Jose's obligations?
