If the CP of 13 bats is Rs 390. What is the price when it is sold at 10% loss?

Options

A. Rs 200
B. Rs 300
C. Rs 350
D. None of these

Answer

To solve the problem step by step, let's break it down:

### Step 1: Find the Cost Price (CP) of one bat.
Given that the cost price of 13 bats is Rs 390, we can find the cost price of one bat by dividing the total cost price by the number of bats.

\[ \text{CP of 1 bat} = \frac{\text{Total CP}}{\text{Number of bats}} = \frac{390}{13} = 30 \text{ Rs} \]

### Step 2: Calculate the Selling Price (SP) at 10% loss.
To find the selling price when sold at a 10% loss, we first need to determine what 10% of the cost price of one bat is.

\[ \text{Loss} = 10\% \text{ of CP} = 10\% \text{ of } 30 = \frac{10}{100} \times 30 = 3 \text{ Rs} \]

Now, we subtract the loss from the cost price to find the selling price.

\[ \text{SP} = \text{CP} - \text{Loss} = 30 - 3 = 27 \text{ Rs} \]

### Step 3: Calculate the Total Selling Price for 13 bats.
Now that we have the selling price for one bat, we can find the total selling price for 13 bats by multiplying the selling price of one bat by the number of bats.

\[ \text{Total SP} = \text{SP of 1 bat} \times \text{Number of bats} = 27 \times 13 \]

Calculating this gives:

\[ 27 \times 13 = 351 \text{ Rs} \]

### Conclusion:
The total selling price when all 13 bats are sold at a 10% loss is Rs 351.

### Final Answer:
None of the given options (200, 300, 350) match the calculated total selling price of Rs 351, so the answer is "none of these."
