Understanding the Selling Price and Profit
The shopkeeper sells an item for Rs. 870 and makes a profit of 20%. To determine the cost price (CP) of the item, we can use the formula for profit:
- Profit = Selling Price - Cost Price
- Profit Percentage = (Profit / Cost Price) * 100
Given that the profit percentage is 20%, we can rearrange the formula to find the Cost Price.
Calculating the Cost Price
- Selling Price (SP) = Rs. 870
- Profit Percentage = 20%
Using the relationship:
CP = SP / (1 + Profit Percentage/100)
Substituting the values:
CP = 870 / (1 + 20/100) = 870 / 1.2 = Rs. 725
Calculating the Selling Price for 50% Profit
Next, to find the new selling price for a 50% profit, we again apply the profit formula:
- Desired Profit Percentage = 50%
Using the formula:
New SP = CP * (1 + Desired Profit Percentage/100)
So:
New SP = 725 * (1 + 50/100) = 725 * 1.5 = Rs. 1087.50
Conclusion
To achieve a profit of 50%, the shopkeeper should sell the item for Rs. 1087.50. Thus, the correct answer is option 'D'.
