Calculation of Profit/Loss Percentage
- Cost price of 15 notebooks = Rs. 400
- Cost price per notebook = 400/15 = Rs. 26.67
- Selling price of 10 notebooks = Rs. 300
- Selling price per notebook = 300/10 = Rs. 30
- Total selling price of 15 notebooks = 30 x 15 = Rs. 450
- Profit = Total selling price - Total cost price = 450 - 400 = Rs. 50
- Profit percentage = (Profit/Cost price) x 100 = (50/400) x 100 = 12.5%
Explanation
In this question, we are given the cost price of 15 notebooks, which is Rs. 400. We are also given the selling price of 10 notebooks, which is Rs. 300. To find the profit or loss, we need to calculate the cost price per notebook and the selling price per notebook.
First, we find the cost price per notebook by dividing the total cost price by the number of notebooks purchased. So, the cost price per notebook is Rs. 26.67.
Next, we find the selling price per notebook by dividing the total selling price by the number of notebooks sold. So, the selling price per notebook is Rs. 30.
Now, we can calculate the total selling price of 15 notebooks by multiplying the selling price per notebook by the number of notebooks purchased. So, the total selling price of 15 notebooks is Rs. 450.
To calculate the profit, we subtract the total cost price from the total selling price. So, the profit is Rs. 50.
Finally, we calculate the profit percentage by dividing the profit by the cost price and multiplying by 100. So, the profit percentage is 12.5%.
Therefore, Sneha made a profit of 12.5% by selling 15 notebooks at the rate of 10 notebooks for Rs. 300.
