1. **State the problem:** Calculate the simple interest $I$ using the formula $I = PRT$ where $P$ is the principal, $R$ is the rate of interest per year (in decimal), and $T$ is the time in years. 2. **Given values:** Principal $P = 10000$ (RM10000). The other values RM1000, RM1400, RM14000, and RM14 appear to be possible interest amounts or rates, but we need the rate $R$ and time $T$ to calculate interest. 3. **Formula:** $$I = P \times R \times T$$ 4. **Explanation:** To find the interest $I$, you multiply the principal amount by the rate (expressed as a decimal) and the time period in years. 5. **Since the problem does not specify $R$ or $T$, we cannot calculate $I$ exactly.** 6. **If you provide the rate and time, I can calculate the interest for you.**
