Dipper has a 10 year increasing annuity immediate that pays $100 at the end of the first year, $200 at the end of the second year, ... , and $1000 at the end of the 10th year. He exchanges the annuity for a perpetuity of equal value that pays X at the end of each year. If the effective annual interest rate is 3%, find the value of X

Dipper has 10 year increasing annuity immediate that pays $100 at the end of the first year, $200 at the end of the second year and so on uptill $1000 at the end of the 10th year.
He exchanges this annuity with perpetuity of equal value that pays X at the end of the each year. Effective Annual Interest Rate is 3%.
To calculate the value of X, we must compute the present value of annuity and perpetuity and equate the both cashflows.

| Time | Cash Flows | Present Value Factor | Present Value |
| 1 | $100.00 | 0.970873786 | $97.09 |
| 2 | $200.00 | 0.942595909 | $188.52 |
