The price of a sweater was slashed from Rs. 960 to Rs. 816 by a shopkeeper in the winter season. Find the rate of discount given by him.

Answer

To find the rate of discount given by the shopkeeper, we can follow these steps:

### Step 1: Identify the Original Price and the Selling Price
- The original price of the sweater (marked price) is Rs. 960.
- The selling price after the discount is Rs. 816.

### Step 2: Calculate the Discount Amount
- The discount amount can be calculated using the formula:
\[ \text{Discount} = \text{Original Price} - \text{Selling Price} \]
- Substituting the values:
\[ \text{Discount} = 960 - 816 = 144 \]
- So, the discount amount is Rs. 144.

### Step 3: Calculate the Rate of Discount
- The rate of discount can be calculated using the formula:
\[ \text{Rate of Discount} = \left( \frac{\text{Discount}}{\text{Original Price}} \right) \times 100 \]
- Substituting the values:
\[ \text{Rate of Discount} = \left( \frac{144}{960} \right) \times 100 \]
- Simplifying the fraction:
\[ \text{Rate of Discount} = 0.15 \times 100 = 15\% \]

### Final Answer
The rate of discount given by the shopkeeper is **15%**.
