Solutions

Expert Solution

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.
