The cost price of a bat is 75% of the marked price. Calculate the gain percentage after allowing a discount of 15%.

Correct option is B

Given:

The cost price of a bat is 75% of the marked price.
Discount % = 15%
Formula Used:
Selling price = Marked Price - Discount
Profit = Selling Price - Cost Price
​$$\text{Profit \%} = \frac{\text{Profit}}{\text{Cost Price}} \times 100$$​​
Solution:
Let the marked price be = 100
So, the cost price = 100 × $$\frac{75}{100}$$​ = 75

Selling price = 100 - 100 × $$\frac{15}{100} = 85$$​​
Profit = 85 - 75 = 10
Profit percentage = $$\frac{10}{75}$$​ × 100
∴The profit percent is 13.33%
