Write a program that find "Monthly installment" and "total amount" of the loan based on the following equation

Years

Total Amount $=$ Loan $+(1+00$

Monthly installment $=$ Total Amount $/($years $12)$

Where $($i$)$ is the interest rate and based on the age of the borrower.

If the age is less than or equal $25$ the Interest rate $=3\mathrm{.}5,$

If the age is less than or equal $35$ and greater than $25$ the interest rate $=4\mathrm{.}5,$

If the age is greater $35$ the interest rate $=5\mathrm{.}5.$
