Five years ago a business borrowed $100,000 agreeing to repay the principal and all accumulated interest at 8% pa compounded quarterly, 8 years from the loan date. Two years after the first borrowing, the business approached the same lender for a second loan. The lender agreed to a loan of $200,000 to be repaid with all accumulated interest at 6%pa effective 10 years from the loan date. Today the borrower approaches the lender with a proposal to discharge BOTH loans by equal payments at the ends of years 1, 3 and 4 and a cash payment of $50,000 at the end of year 6 from the present. If money is worth 5.25% pa effective, determine the size of the proposed repayments.
