Final answer:
To make a 30% profit, Hari would need to sell the goods at approximately RS. 139 per kg when considering the purchase and transportation costs.
Step-by-step explanation:
The subject of this question is Mathematics, and it relates to the concept of calculating profit after factoring in the cost of transportation. Hari bought 225kg of a product at RS. 100 per kg and 200kg at the same rate. Including RS. 3000 for transportation, we need to determine the selling price per kg if he wishes to make a profit of 30%.
To calculate the total cost:
Cost of 225kg = 225 * 100 = 22500 RS.
Cost of 200kg = 200 * 100 = 20000 RS.
Total cost = 22500 + 20000 + 3000 (transportation) = 45500 RS.
To make a 30% profit, we calculate:
Total cost including profit = 45500 * 1.30 = 59150 RS.
Total kg purchased = 225 + 200 = 425kg.
Selling price per kg = Total cost including profit / Total kg = 59150 / 425 = 139.17 RS.
Since prices are usually rounded to the nearest whole number, Hari would need to sell at approximately RS. 139 per kg to achieve a 30% profit margin.
