Question: 03 Marks: 10

If and are the means for the two sets and respectively and related by and . Then find the values of ‘ ’ and ‘ ’.

.................

This is a Future Value of an Ordinary Annuity problem.

Future Value is 40,000. Number of periods is 20. Annual rate is 8% 

From TVM table for FV of an Annuity, the Factor is 45.7625

The FV = Annuity x Factor. We know the FV is 40,000, so divide it by the factor of 45.7625 to determine the Annuity amount of 874.08

The formula is ((1+ r)^n - 1) / r, or ((1.08)^20 - 1) / .08, or 4.661 - 1 = 3.661 / .08 = 45.7625
