**1.1 Simple Interest for Odd Period, Compound Interest for Rest**\r
\n" ); document.write( "\n" ); document.write( "* **Calculate the odd period:**
\n" ); document.write( " * From March 10, 2020, to July 1, 2020, is approximately 3 months.\r
\n" ); document.write( "\n" ); document.write( "* **Calculate simple interest for the odd period:**
\n" ); document.write( " * Principal (P) = R10,000
\n" ); document.write( " * Rate (R) = 16.5% per annum = 0.165
\n" ); document.write( " * Time (T) = 3 months = 3/12 years = 0.25 years
\n" ); document.write( " * Simple Interest (SI) = P * R * T = R10,000 * 0.165 * 0.25 = R412.50\r
\n" ); document.write( "\n" ); document.write( "* **Calculate the amount after the odd period:**
\n" ); document.write( " * Amount = Principal + Simple Interest = R10,000 + R412.50 = R10,412.50\r
\n" ); document.write( "\n" ); document.write( "* **Calculate the remaining period:**
\n" ); document.write( " * From July 1, 2020, to July 1, 2025, is 5 years.\r
\n" ); document.write( "\n" ); document.write( "* **Calculate the amount after 5 years with compound interest:**
\n" ); document.write( " * Principal (P) = R10,412.50
\n" ); document.write( " * Rate (R) = 16.5% per annum compounded semi-annually = 0.165 / 2 = 0.0825 per half-year
\n" ); document.write( " * Number of periods (n) = 5 years * 2 periods/year = 10 periods
\n" ); document.write( " * Amount = P * (1 + R)^n = R10,412.50 * (1 + 0.0825)^10
\n" ); document.write( " * Amount ≈ R23,967.47\r
\n" ); document.write( "\n" ); document.write( "**1.2 Fractional Compounding**\r
\n" ); document.write( "\n" ); document.write( "* **Calculate the total number of days:**
\n" ); document.write( " * From March 10, 2020, to July 1, 2025, is approximately 1826 days.\r
\n" ); document.write( "\n" ); document.write( "* **Calculate the daily interest rate:**
\n" ); document.write( " * Annual interest rate = 16.5% = 0.165
\n" ); document.write( " * Daily interest rate = 0.165 / 365 \r
\n" ); document.write( "\n" ); document.write( "* **Calculate the amount with daily compounding:**
\n" ); document.write( " * Amount = P * (1 + (R/365))^N
\n" ); document.write( " * Amount = R10,000 * (1 + (0.165/365))^1826
\n" ); document.write( " * Amount ≈ R24,178.12\r
\n" ); document.write( "\n" ); document.write( "**Comparison**\r
\n" ); document.write( "\n" ); document.write( "* **Method 1 (Simple + Compound):** R23,967.47
\n" ); document.write( "* **Method 2 (Fractional Compounding):** R24,178.12\r
\n" ); document.write( "\n" ); document.write( "**Conclusion**\r
\n" ); document.write( "\n" ); document.write( "Fractional compounding (daily compounding in this case) results in a slightly higher accumulated amount compared to using simple interest for the odd period and then switching to semi-annual compounding. This is because fractional compounding applies interest more frequently, leading to slightly higher returns.\r
\n" ); document.write( "\n" ); document.write( "**Note:**\r
\n" ); document.write( "\n" ); document.write( "* This calculation assumes a year has 365 days.
\n" ); document.write( "* Slight variations in the exact number of days and rounding may result in minor differences in the final amounts.
