Answer

To find the percentage increase in a person's salary from Rs. 14,400 to Rs. 16,200, we can follow these steps:

### Step 1: Calculate the increase in salary
To find the increase in salary, we subtract the old salary from the new salary.

\[ \text{Increase in Salary} = \text{New Salary} - \text{Old Salary} = 16200 - 14400 \]

\[ \text{Increase in Salary} = 1800 \]

### Step 2: Use the percentage increase formula
The formula for calculating percentage increase is:

\[ \text{Percentage Increase} = \left( \frac{\text{Increase in Salary}}{\text{Old Salary}} \right) \times 100 \]

### Step 3: Substitute the values into the formula
Now we substitute the values we have into the formula:

\[ \text{Percentage Increase} = \left( \frac{1800}{14400} \right) \times 100 \]

### Step 4: Simplify the fraction
We can simplify the fraction:

\[ \frac{1800}{14400} = \frac{1}{8} \]

### Step 5: Multiply by 100
Now we multiply by 100 to find the percentage:

\[ \text{Percentage Increase} = \left( \frac{1}{8} \right) \times 100 = 12.5 \]

### Final Answer
Thus, the percentage increase in the person's salary is:

\[ \text{Percentage Increase} = 12.5\% \]
