The simple interest on $₹73,000$ at the rate of $15\%$ per annum from 12-02-2022 to 11-02-2023 is :

Step 1: Calculate the exact time period
The period is from 12-02-2022 to 11-02-2023.
Since 2022 is a non-leap year (28 days in February), let's count the number of days:

* Feb 2022: $28-12=16\text{ days}$ (excluding Feb 12, or including one endpoint)
Alternatively, from 12-02-2022 to 11-02-2023 is exactly $1\text{ full year}$ (consisting of $365\text{ days}$ as 2022 is not a leap year and 2023 is also not a leap year).
Let's verify by total days:
* Feb 2022: $16\text{ days}$ (from 13th to 28th)
* Mar 2022: $31\text{ days}$
* Apr 2022: $30\text{ days}$
* May 2022: $31\text{ days}$
* Jun 2022: $30\text{ days}$
* Jul 2022: $31\text{ days}$
* Aug 2022: $31\text{ days}$
* Sep 2022: $30\text{ days}$
* Oct 2022: $31\text{ days}$
* Nov 2022: $30\text{ days}$
* Dec 2022: $31\text{ days}$
* Jan 2023: $31\text{ days}$
* Feb 2023: $11\text{ days}$ (up to 11th)

Total days = $16+31+30+31+30+31+31+30+31+30+31+31+11=365\text{ days}$.
Therefore, Time ($T$) = $\frac{365}{365}=1\text{ year}$.

Step 2: Calculate Simple Interest
Given: Principal ($P$) = $₹73,000$, Rate ($R$) = $15\%$, Time ($T$) = $1\text{ year}$.

$$\text{SI}=\frac{P\times R\times T}{100}$$

$$\text{SI}=\frac{73,000\times 15\times 1}{100}=730\times 15=₹10,950$$
