Options

A. 24
B. 15
C. 25
D. 20

Answer

To find the discount percentage on the watch, we can follow these steps:

### Step 1: Identify the Marked Price (MP) and Selling Price (SP)
- The marked price (MP) of the watch is Rs 8,500.
- The selling price (SP) of the watch is Rs 7,225.

### Step 2: Calculate the Discount Amount
To find the discount amount, we subtract the selling price from the marked price:
\[ \text{Discount} = \text{MP} - \text{SP} \]
\[ \text{Discount} = 8500 - 7225 \]
\[ \text{Discount} = 1275 \]

### Step 3: Calculate the Discount Percentage
To find the discount percentage, we use the formula:
\[ \text{Discount Percentage} = \left( \frac{\text{Discount}}{\text{MP}} \right) \times 100 \]
Substituting the values we found:
\[ \text{Discount Percentage} = \left( \frac{1275}{8500} \right) \times 100 \]
\[ \text{Discount Percentage} = 0.15 \times 100 \]
\[ \text{Discount Percentage} = 15\% \]

### Final Answer
The discount at which the watch is being sold is **15%**.
