Explanation:

- You invested Rs.12,500 at 12% per annum on compound interest.

- The investment period is 1 year and 4 months.

- Compound annually means interest is calculated once a year.

- First, calculate for the 1 year:

$$A=P(1+r{)}^n=12500\times (1+0.12{)}^1=12500\times 1.12=14000$$

- For the remaining 4 months (1/3 of a year), calculate simple interest on Rs.14,000:

$$\text{Simple Interest}=\frac{P\times r\times t}{100}=\frac{14000\times 12\times \frac{1}{3}}{100}=560$$

- Add simple interest to the amount after first year:

$$14000+560=14560$$

- Rs.14,560 is the final amount.

- Correct Answer: Option 2: Rs.14,560
