Final answer:
The selling price for each ropani to achieve a 20% profit would be Rs. 5,35,000. However, this is not listed in the options provided which suggests a possible error in the question or options.
Step-by-step explanation:
Bibek bought 6 ropani of land at the rate of Rs. 3,25,000 per ropani and spent an additional Rs. 7,25,000 for the boundary wall. If he wishes to make a 20% profit on his total investment, we must calculate the total cost first, and then find the price that would give him his desired profit margin.
First, we calculate the total cost of the land (6 ropani × Rs. 3,25,000) and add the cost of the boundary wall:
- Total cost of land = Rs. 3,25,000 × 6 = Rs. 19,50,000
- Boundary wall cost = Rs. 7,25,000
- Total cost = Land + Wall = Rs. 19,50,000 + Rs. 7,25,000 = Rs. 26,75,000
Next, we determine the desired total selling price by including the 20% profit:
- Desired profit = 20% of Rs. 26,75,000 = 0.20 × Rs. 26,75,000 = Rs. 5,35,000
- Total selling price = Total cost + Desired profit = Rs. 26,75,000 + Rs. 5,35,000 = Rs. 32,10,000
Finally, we calculate the selling price per ropani:
- Selling price per ropani = Total selling price / 6 = Rs. 32,10,000 / 6 = Rs. 5,35,000
Therefore, the correct selling price for each ropani to achieve a 20% profit would be Rs. 5,35,000, which is not listed in the options provided. There might be a mistake in the options or in the original question. Please review the options or check the question for accuracy.
