So, if you invest R1,500 for 1 year at an interest rate of 3.5%, the interest at the end of the year would be R52.50.

Thus R1,500 invested for 1 year at 3.5% interest will earn R52.50. That’s easy!

Thus R1,500 invested for 1 year at 3.5% interest will earn R52.50. That’s easy!
To calculate what the monthly interest is, simply divide 52.50 by 12 and you will get R4.38 (rounded up) interest for 1 month. You could be more accurate and divide 52.5 by 365.4 (number of days in the year) and then multiply by th... |
