How long will it take $10,000 to reach $50,000 if it earns 10% annual interest compounded semiannually?
You get a twenty-year amortized loan of $100,000 with a 5% annual interest rate. What are the annual payments?
You get a 25-year loan of $150,000 with an 8% annual interest rate. What are the annual payments?
1)
FV = PV * (1+ rate/2) ^number of semi-annual period
50000 = 10000 * (1+0.10/2)^number of semi-annual period
5 = (1+0.10/2)^number of semi-annual period
Taking Log on both side
Log(5) = number of semi-annual period * Log(1+0.05)
Number of semi-annual period = 32.986
Number of years = 16.49 Answer
Option C is correct.
2)
Loan Amount = Present Value of annual payments discounted @5%
Rate =5%
Number of payments = 20
100000 = Annual Payments * (1/(1+0.05)^1 +1/(1+0.05)^2 +1/(1+0.05)^3 +1/(1+0.05)^4 +1/(1+0.05)^5 +1/(1+0.05)^6 +........1/(1+0.05)^20 )
100000 = Annual Payments * 12.46
Annual Payments = 8024.26 Answer
Option D is correct.
3)
Loan Amount = Present Value of annual payments discounted @ 8%
150000 = Annual Payments * (1/(1+0.08)^1 +1/(1+0.08)^2 +1/(1+0.08)^3 +1/(1+0.08)^4 +1/(1+0.08)^5 +1/(1+0.08)^6 +........1/(1+0.08)^25 )
150000 = Annual Payments * 10.67
Annual Payments = 14051.82 Answer
Option A is correct.
