Question: Zeda, Inc., a U.S. MNC, is considering making a fixed direct investment in Denmark.The Danish government has offered Zeda a concessionary loan of DKK15,000,000 at a rate of 4 percent per annum.The normal borrowing rate is 6 percent in dollars and 5.5 percent in Danish krone.The loan schedule calls for the principal to be repaid in three equal annual installments.What is the present value of the benefit of the concessionary loan?The current spot rate is DKK5.60/$1.00 and the expected inflation rate is 3% in the U.S. and 2.5% in Denmark.

I have found the solution but I couldn't really understand the steps. May I get someone to explain it to me?

(p/s: how much do I need to pay for asking question?)
