1. As part of the promotion to encourage young executive to buy Yaris, Toyota offers the choice of either a 9-year FlexiPlan or a Shariah-Compliant Islamic Financing (AITAB). For the Flexiplan, a buyer can enjoy a lower monthly installment for the first 3 years and pay double of the instalment for the remaining 6 years. The AITAB offers buyer the option for either a 5-year, 7-year or 9-year fixed monthly installments at 3% p.a interest rate. Assume that the loan approved is for RM75,000. a) Determine the monthly instalments for all the AITAB 5-year, 7-year and 9-year plans respectively. b) If the installment for the first 3 years of the Flexiplan is to be set at RM700, determine how much will the installment be for the remaining 6 years. c) Assuming that you would be able to raise an additional cash of RM50 every month in the final 4 years to top up (after year 5) of the Flexiplan, determine how many months will you be able to reduce the payment payback period. d) Assuming that you prefer to pay an ever increasing payment Flexiplan starting with RM500 in the first month and slowly increased by RM10 every month, estimate how many months would your commitment be.
