By investing Rs 10,000 in the shares of a company, a man gets an income of Rs 800, the dividend being 10%. If the face-value of each share is Rs 100, Find:
the rate percent which the person earns on his investment.

Answer

To find the rate percent which the person earns on his investment, we can follow these steps:

### Step 1: Identify the given values
- Investment amount (I) = Rs 10,000
- Income from shares (E) = Rs 800

### Step 2: Use the formula for rate percent
The formula to calculate the rate percent (R) is given by:

\[ R = \left( \frac{E}{I} \right) \times 100 \]

### Step 3: Substitute the values into the formula
Substituting the known values into the formula:

\[ R = \left( \frac{800}{10000} \right) \times 100 \]

### Step 4: Calculate the fraction
Now, calculate the fraction:

\[ \frac{800}{10000} = 0.08 \]

### Step 5: Multiply by 100 to find the rate percent
Now, multiply by 100 to convert it into percentage:

\[ R = 0.08 \times 100 = 8\% \]

### Final Answer
The rate percent which the person earns on his investment is **8%**.
