SSC Constable GD Paper : Elementary Mathematics

Solution

Let the selling price (SP) of the article be ( x ). The cost price (CP) is given as 5/8 of the selling price. Therefore:

CP = $\frac{5}{8} \times x = \frac{5x}{8}$

The profit is the difference between the selling price and the cost price:
Profit = SP – CP = $x - \frac{5x}{8} = \frac{8x - 5x}{8} = \frac{3x}{8}$

The profit percentage is calculated as:
Profit Percentage = $\frac{\text{Profit}}{\text{CP}} \times 100 = \frac{\frac{3x}{8}}{\frac{5x}{8}} \times 100 = \frac{3}{5} \times 100 = 60\%$

Thus, the profit percentage is 60%.
