i) Compounding is continuously and payments are made biennially
ii) Compounding and payments are both made semi-annually
iii) Compounding is monthly and payments are made quarterly
iv) Compounding is quarterly and payments are made annually
If loan is for $30000, compute amount of every loan payment in each case (i - iv).
