एक सुपरमार्केट में दुकानदार ने कीमत में 30% की वृद्धि करने के बाद 20% की छूट की घोषणा की। तो फिर उसे उस वस्तु पर कितना लाभ होगा जिसकी वास्तविक कीमत 300 रुपये है?

Explanation

Let's analyze the problem step-by-step:

• Actual cost price (CP): Rs 300
• Price increased by 30%: New price = 300 + 30% of 300 = 300 + 90 = Rs 390
• Discount offered: 20% on the increased price
• Discount amount: 20% of 390 = Rs 78
• Selling price (SP): 390 − 78 = Rs 312
• Profit: SP − CP = 312 − 300 = Rs 12

🎯 Final Answer: Rs 12 profit
