Final answer:
After calculating the total cost including the price of goods and transportation, and adding a 30% profit margin, Haru's selling price per kg would need to be RS. 249.17 to achieve the desired profit. The given options do not match this calculated selling price.
Step-by-step explanation:
The question requires calculating the selling price per kilogram that Haru should set to make a profit of 30% after buying 300kg of product at different prices and including the cost of transportation. To find the selling price, we first calculate the total cost for Haru, which includes the cost of purchase plus the transportation fee. Then, we add the desired profit margin of 30% to obtain the total selling price, and finally, we divide this by the total weight to get the selling price per kilogram.
First, we calculate the cost price for 100kg at RS. 225/kg and 200kg at RS. 160/kg:
- 100kg × RS. 225/kg = RS. 22,500
- 200kg × RS. 160/kg = RS. 32,000
Next, we add both amounts and include transportation:
Total cost = RS. 22,500 + RS. 32,000 + RS. 3000 (transportation) = RS. 57,500
To find the total selling price with a 30% profit, we calculate:
Total selling price = Total cost × (1 + Profit%) = RS. 57,500 × (1 + 0.30) = RS. 74,750
Now, we find the selling price per kilogram by dividing the total selling price by the total weight:
Selling price per kg = Total selling price / Total weight = RS. 74,750 / 300kg = RS. 249.17 per kg
None of the given options (a) RS. 300, (b) RS. 320, (c) RS. 340, (d) RS. 360 exactly match the calculated selling price of RS. 249.17 per kg. Therefore, Haru must consider adjusting the desired profit or reevaluate the final selling price options.
