The following is a good APGP practice question from AJC. Personally, I feel that its well set and tests students on their concepts and understanding.

Mary has a monthly income of 40,000 for 6 years which charges an interest rate of 3.00% per annum, compounded monthly. Interest is chargeable immediately when the loan sum is drawn out. The monthly repayment, latex mlatex n^(th)latex 40000(\frac {(401)}{400})^n-400m((\frac {401}{400})^n-1)$.

Do give it an attempt and see if you can show as required. Share with me if there are any doubts.
