Correct Answer - Option 1 : 12.5%
Given:
Discount percent = 10
Market price = cost price + 25% of cost price
Formula used:
Profit = selling price – cost price
Selling price = market price – discount
Calculation:
Let the cost price is Rs. 100
So, Market price is Rs. 125
Selling price = Rs. 125 – 10% of 125
⇒ Rs. 112.5
Profit = 112.5 – 100
⇒ Rs. 12.5
Profit% = [(12.5/100) × 100]%
∴ The gain percent is 12.5%
