Options

A. 4
B. 8
C. 12
D. 16

Answer

To find the percentage decrease in the value of the company stock, we can follow these steps:

### Step 1: Determine the original price and the new price.
- Original price of the stock = Rs. 25
- New price of the stock = Rs. 21

### Step 2: Calculate the decrease in price.
- Decrease in price = Original price - New price
- Decrease in price = Rs. 25 - Rs. 21 = Rs. 4

### Step 3: Use the formula for percentage decrease.
The formula for percentage decrease is given by:

\[ \text{Percentage Decrease} = \left( \frac{\text{Decrease in Price}}{\text{Original Price}} \right) \times 100 \]

### Step 4: Substitute the values into the formula.
- Decrease in price = Rs. 4
- Original price = Rs. 25

Substituting the values, we get:

\[ \text{Percentage Decrease} = \left( \frac{4}{25} \right) \times 100 \]

### Step 5: Calculate the percentage decrease.
- First, calculate \( \frac{4}{25} \):
\[ \frac{4}{25} = 0.16 \]
- Now, multiply by 100:
\[ 0.16 \times 100 = 16 \]

### Final Answer:
The percentage decrease per share is **16%**.
