Detailed Solution

Concept: We will solve this question by using the formula

Loss % = \frac{loss}{cost price} \times 100

then we will be calculating the price of 13 bat sold at 10% loss by subtracting loss from the present cost price of 13 bats.
Price of 13 bats

= Rs . 390

Now we will find the cost of 13 bats when it's sold at 10% loss. We should first find out the loss that will occur after selling the bats at 10% loss by substituting the given values in the above formula.

10 = \frac{loss}{390} \times 100

10 = \frac{loss}{39} \times 10

10 \times 39 = loss \times 10

\frac{10 \times 39}{10} = loss

So, we know that there will be a loss of Rs. 39.
Now subtract the loss amount from the cost price of 13 bat

390 - 39 = 351

So, the price of 13 bat when it is sold at 10% loss is Rs. 351
Hence, option 4 is correct.
