Answer:
Explanation:
Please note that this question we have to do by hit and trail method. Every annual payment has 2 components,
Interest and Principal repayment
Interest is higher at the beginning and principal repayment is lower. We have not been given the time for the loan.
So i will tell you how to calculate the Total annual installment by hand
and then we will make table of payments to see if we are getting 450 principal repayment in month 4
We will do 3-4 iterations to get the answer
Loan Amount = 20,000
Rate = 4%
Principal repayment in year 4 = 450
Let say time = n years
Annual installment = Loan amount * ( rate * ( 1+rate ) ^n ) / ( ( 1 + rate ) ^n -1 )
assume n = 25 years
Annual installment = 20,000 * ( 0.04* ( 1.04 ) ^ 25 ) / ( ( 1.04 ) ^25 -1 ) = 1280.24
