- Rate applied = 7% + 0% = 7%.
- Term = 5 years = 5 years, giving n t = 4 x 5 = 20 compounding periods.
- Maturity value = P (1 + R/(100 n))^(n t) = 100000 x (1 + 7/(100 x 4))^20 = 141477.82.
- Interest earned = maturity - principal = 41477.82.
- Effective annual yield = (1 + R/(100 n))^n - 1 = 7.185903%.
