Understanding the problem:
Principal amount (P) = R1 500
Interest rate (R) = 6.57% per year
Time (T) = 16 months
Formula for Simple Interest:
Simple Interest (SI) = (P * R * T) / 100
Calculations:
1. Convert months to years: 16 months = 16/12 = 4/3 years
2. Calculate Simple Interest: SI = (1500 * 6.57 * 4/3) / 100 = R131.40
3. Calculate the balance: Balance = Principal + Simple Interest = 1500 + 131.40 = R1631.40
Answer:
The balance in the account 16 months later is R1 631.40.
Therefore, the correct option is c. R1 631.40.

Understanding the problem:
We need to find the time it takes for a principal (P) to quadruple its value.
Interest rate (r) = 12% per annum compounded monthly.
Formula for compound interest:
A = P(1 + r/n)^(nt)
o A is the future value
o P is the principal
o r is the annual interest rate (as a decimal)
o n is the number of times interest is compounded per year
o t is the number of years

Given:
A = 4P (since we want the principal to quadruple)
r = 12% = 0.12
n = 12 (compounded monthly)
