Correct Answer - Option 1 : 33.33% profit
Formula used:
Profit = SP - CP
Profit % = (Profit/CP) × 100
Here, SP → Selling price, CP → Cost price
Calculation:
A man buys 10 pens for Rs.15
Cost of 1 pen = 15/10 = Rs. 1.5
Selling price of 1 pen = Rs. 2
Profit = SP - CP = 2 - 1.5 = Rs. 0.5
Profit % = (Profit/CP) × 100
⇒ (0.5/1.5) × 100 = 33.33%
∴ The profit percent is 33.33%
