The cost of the book is P1,000,000 which will amortized for 3 years monthly but he will start paying 8 months after the loan is given and must be finished at the end of 3 years. How much is the end of month amortization?

Mr. Shark deposited P40000, P50000, and P70000 at year 1, 5, and 9 which is 10% effective. Replace this by an equivalent end of month amortization for 9 years.
