Answer

To find the value of 25% of 10% of Rs. 800, we can follow these steps:

### Step 1: Calculate 10% of Rs. 800
To find 10% of Rs. 800, we can use the formula:
\[ 10\% \text{ of } 800 = \frac{10}{100} \times 800 \]
Calculating this gives:
\[ 10\% \text{ of } 800 = 0.1 \times 800 = 80 \]

### Step 2: Calculate 25% of the result from Step 1
Now that we have 10% of Rs. 800, which is Rs. 80, we need to find 25% of Rs. 80:
\[ 25\% \text{ of } 80 = \frac{25}{100} \times 80 \]
Calculating this gives:
\[ 25\% \text{ of } 80 = 0.25 \times 80 = 20 \]

### Final Answer
Thus, the value of 25% of 10% of Rs. 800 is Rs. 20.
