If the cost price of 25 articles is equal to the selling price of 35 articles find the profit/loss percentage.

Loss — 28.57%

Cost price of 25 articles = Selling price of 35 articles

\(\frac{(cost price of one article)}{ (selling price of one article)}\)  = \(\frac{325}{35}\) = \(\frac{5}{7}\)

Profit% = \(\frac{( 7 - 5 )}{7}\) × 100 = Loss — 28.57%
