Solution :
Annual payment = [tex]$\$ 5000$[/tex]
1. The rate of interest annually = 12%
Present value [tex]$=\$5000 \times \text{PVA of} \ \$1(12\%, 5)$[/tex]
[tex]$=\$5000 \times 3.60478$[/tex]
= $ 18,023.90
2. The rate of interest annually = 12%
Present value [tex]$=\$5000 \times \text{PVAD of} \ \$1(12\%, 5)$[/tex]
[tex]$=\$5000 \times 4.03735$[/tex]
= $ 20,186.75
3. The rate of interest annually = 12%
The rate of interest quarterly = 3%
Present value = [tex]$\$5000 \times \text{PV of} \ \$1(3\%, 4) + \$5000 \times \text{PV of} \ \$1(3\%, 8) +\$5000 \times \text{PV of} \ \$1(3\%, 12) $[/tex] [tex]$+\$5000 \times \text{PV of} \ \$1(3\%, 16) + \$5000 \times \text{PV of} \ \$1(3\%, 16)$[/tex]
[tex]$= \$5000 \times 0.88849 + \$5000 \times 0.78941 + \$5000 \times 0.70138 + \$5000 \times 0.62317 + \$5000 \times 0.55368$[/tex][tex]$=\$ 17,780.65$[/tex]
