Angel owes his creditor a) P 1,000 due without interest at the end of 10 years, and b)
P 3,000 due at the end of 4 years with accumulated interest from today at 4% compounded annually. Angel will discharge her obligations by two equal payments at the ends of the 3rd and 6th years. If the creditor states that the money is worth 6% compounded semiannually, find the new payments.

How do I answer this

Beyonce borrowed P 2000 from Mariah on June 1, 1975, and P 500 on June 1, 1977, agreeing that money is worth 5 % compounded annually. Beyonce paid P 500 on June 1, 1978, P 400 on June 1, 1979, and P 700 on June 1, 1980. What additional sum should Beyonce pay on June 1, 1983, to discharge all remaining liability?
