D. None of these

Answer

To solve the problem step by step, we can follow these instructions:

### Step 1: Determine Raju's Monthly Salary
We know that 27% of Arun's monthly salary is equal to Raju's monthly salary. Given that Arun's monthly salary is Rs. 25,000, we can express this mathematically:

\[ Raju's\ Monthly\ Salary = 27\% \times Arun's\ Monthly\ Salary \]

Substituting Arun's salary:

\[ Raju's\ Monthly\ Salary = 27\% \times 25000 \]

### Step 2: Calculate 27% of Rs. 25,000
To find 27% of Rs. 25,000, we convert the percentage into a decimal:

\[ 27\% = \frac{27}{100} = 0.27 \]

Now, we can calculate:

\[ Raju's\ Monthly\ Salary = 0.27 \times 25000 \]

Calculating this gives:

\[ Raju's\ Monthly\ Salary = 6750 \]

### Step 3: Calculate Raju's Annual Salary
To find Raju's annual salary, we multiply his monthly salary by 12 (the number of months in a year):

\[ Raju's\ Annual\ Salary = Raju's\ Monthly\ Salary \times 12 \]

Substituting the monthly salary we found:

\[ Raju's\ Annual\ Salary = 6750 \times 12 \]

Calculating this gives:

\[ Raju's\ Annual\ Salary = 81000 \]

### Final Answer
Raju's annual salary is Rs. 81,000.
