If the selling price and cost price of a shirt are \( ₹ 1050 \) and ₹ 900 respectively, then what is the profit percentage?

To find the profit percentage, you first calculate the profit, which is the selling price minus the cost price. So, \( ₹ 1050 - ₹ 900 = ₹ 150 \) profit. Next, to calculate the percentage, you divide the profit by the cost price and then multiply by 100. Thus, \( \frac{150}{900} \times 100 = 16.67\% \). So, the profit percentage is approximately 16.67%. Profit percentages can be very useful in everyday life, especially for small business owners, marketers, and anyone involved in sales. Knowing how to calculate this can help you set competitive prices and gauge whether you're making a wise business decision or just giving away your hard-earned money!
