An investor will receive 4000 at the end of each month. The perpetuity will be paid from 12-year deposits. The term deposit has monthly capitalization and funds were made at the beginning of each month. For six years the interest rate was equal to 4% p.a., for the next six years it was equal to 5% p.a. After ten ears the interest rate will be equal to 3% p.a.

Calculate:

1. The perpetuity value

2. The amount if monthly payment value at term deposit
