STPM 2015 Mathematics (M) Term 3 Assignment

STPM 2015 Term 3 Assignment Coursework Mathematics (M)


Loan repayment can be made based on simple or compound interest. Asset depreciation can be calculated using the flat rate depreciation method or the reducing balance depreciation method.

Sample Question

A brand new car which costs RM 100 000 is bought with a down payment of RM10 000 and a loan of RM90 000.

1. Bank X offers a loan which is to be ammortised with 60 monthly payments at an annual interest rate of 2.5%.
(a) Calculate the monthly payment to amortise the loan.
(b) Construct an amortisation schedule.

2 Bank Y offers a loan which is to he amortised with 60 monthly payments at an annual interest rate of 3% compounded monthly.
(a)    Calculate the monthly payment to amortise the loan.
(b)    Construct an amortisation schedule.

3    Which loan, from Bank X or Bank Y, you would suggest to the car owner? Give your reasons.

4    The car will depreciate to a scrap value of RM40 000 in 5 years.

(a) Using the flat rate depreciation method, find the depreciation rate of the car for the loan from Bank X and construct a table showing the year and the book value.

(b) Using the reducing balance depreciation method, find the depreciation rate of the car for the loan from Bank Y and construct a table showing the year and the book value.

(c) Determine, for each loan, the best year which has the minimum loss to the car owner if the car is to be sold within five years.

  1. jennis

    hi sir! may i ask for question 4c, how to determine the best year to sell the car? thanks

    • KK LEE

      I used the formula stated above. The red one is the best year for me.

    • jennis

      that’s mean the best year to sold is when the depreciation expenses is lowest?

    • KK LEE

      Since it is not mentioned in the question, i used average loss

    • jennis

      thanks sir!

  2. KiaQin

    Hi sir. I would like to know that are the answers for flat rate depreciation and reducing balance depreciation going to be the same?

    • KK LEE

      Hmmm.. In short, finding the average loss per year.

  6. Celice

    Sir, may I ask what should I include in the introduction?

    • KK LEE

      No comment. Thanks

  7. Kevin

    Is it possible to use a different method in determining yearly loss. Can I use the accummulated loss of a present year subtracted by the yearly loss of a previous year to determine yearly loss? My accumulated loss is defined as :present book value-total payment made-downpayment-outsatnding principal balance

    • KK LEE

      It depends on your teacher. I have no answer from your school. 😛

    • Kevin

      Oh ok….Thank you very much for your assistance sir.It is much appreciated.

  8. xuan

    • KK LEE

      As your school teacher said, you can use any methods. So the method i used is to find average loss per year.

  9. Rafie

    Hello sir, i want to ask about question 1.(a) .. can we use the formula such in question 2.(a) ?

    • KK LEE

      Some school teachers said no.

  10. Rafie

    Thank you very much sir ..

  11. Rafie

    sir,based on your answer in 4(C) , so, the best year to sell the car is at the end of the year ?

    • KK LEE


  12. Neoh

    Hi Sir,
    May I ask that:
    Why the formula to calculate the loss do not include the Cost and Loan?
    Since the cost is the cash outflow, and the loan is the cash inflow..
    And the considering of Cost and Loan will also affect amount of the total loss for current year.
    Therefore, may the formula to calculate the loss will be written as below?

    Loss = Loan amount – initial book value + down payment – total payment to bank – loan balance + book value at the current year

    • KK LEE

      You can use any of the formula as long as your teacher accept it.

    • Neoh

      Ok. Thx for answer me.. Have a good day ^^

  13. TAN

    will my answer is wrong? The answer for other questions are the same with you..

    • KK LEE

      It depends on your teacher
