Question

A. 4.5%
B. 18%
C. 9%
D. 2.25%
E. 3%

Answer 1

To determine the half-yearly interest rate, we need to look at the overall growth rate of the investment over one year.

Let's say the investment grows by x% over one year. Then, in half a year, it would grow by x/2%.

Given options:
- A. 4.5%
- B. 18%
- C. 9%
- D. 2.25%
- E. 3%

Let's test each option by calculating the growth rate over one year and then dividing it by 2 to get the half-yearly growth rate:

A. If the half-yearly interest rate is 4.5%, the annual growth rate would be 4.5%*2 = 9%, which does not match the given options.
B. If the half-yearly interest rate is 18%, the annual growth rate would be 18%*2 = 36%, which does not match the given options.
C. If the half-yearly interest rate is 9%, the annual growth rate would be 9%*2 = 18%, which does not match the given options.
D. If the half-yearly interest rate is 2.25%, the annual growth rate would be 2.25%*2 = 4.5%, which does not match the given options.
E. If the half-yearly interest rate is 3%, the annual growth rate would be 3%*2 = 6%, which does not match the given options.

None of the options match the required growth rate of 2.25%.
