Imagine if you had these three credit cards American Express
Solution
Basic Formula
A= P * r(1+r)n
(1+r)n-1
A= EMI Amount
P= Loan Amount (Outstanding Principal of American Express, Citibank and Chase)
r = Rate of Interest
n= No. of Period
Lets solve for American Express Card
Where P= $ 1192, A=$15 is already provided to us. r =4.99% however since monthly payments are made we adjust our r to monthly basis. Therefore (r =4.99%/12 = 0.416% per month)
Now we plug in the above figures and solve for n.
We get n = 96 (Don’t worry if it isn’t exactly 96. Round off differences can occur)
Remember n= 96 is 96 Months!
Similarly Solve for other two
Thus answer to sub question a) is
Answer to Subquestion b)
A prudent person will always think to square off his loan with higher interest first(Citi bank).
Hence all the amount that remains after paying other two lesser interest loans(Chase and American)
i.e Total Payment of $400- $46(chase)-$15(American)= $339 will be used to pay loan of Citibank
Again solve for n using A=339,46,15 respectively
You will require 49 months to square off your entire loan
subquestion d)
It requires us to pay loans with higher interest first and then the loans with lower interest would follow them.
