Abhishek marks the price of his laptop 50 percent above the cost price. He allows his customer a discount of 30 percent on the marked price. What is the profit percentage?

Correct option is A

Given:
- Marked price is 50% above the cost price.
- Discount = 30%.
Formula Used:
- Selling Price (SP) = Marked Price - Discount.
- Profit% = [(SP - Cost Price) / Cost Price] * 100.
Solution:
Let the cost price be Rs. 100.
Then, Marked Price = Rs. 100 + 50% of 100 = Rs. 150.
Selling Price after 30% discount = 150 - 30% of 150 = Rs. 105.
Profit = 105 - 100 = Rs. 5.
Profit% = (5/100) * 100 = 5%.
