1] | The amount to be invested today is the PV of the annuity of $12,000 for 8 years at discounted at 5% = 12000*(1.05^8-1)/(0.05*1.05^8) = | $ 77,558.55 |
2] | The FV of the annuity is to be found out = 2100*(1.03^40-1)/0.03 = | $ 1,58,342.65 |
[It is 40 half years with half yearly interest of 3%] | ||
3] | $40,000 is the FV of the quarterly deposits to be made. | |
Hence, the required quarterly deposit = 40000*0.02/(1.02^20-1) = | $ 1,646.27 | |
[it is 20 quarters with quarterly interest of 2%] | ||
4] | FV of the annuity = 100*(1.015^40-1)/0.015 = | $ 5,426.79 |
[It is 40 quarters with quarterly interest of 1.5%] |
