In a certain store, the profit of an article is 380% of the cost. If the cost increases by 20% but the selling price remains the same, what percentage of the selling price is the profit:

75%

Profit percentage = 380% and Increase in cost price = 20%

The selling price of the articles remains constant.

Percentage of profit = Gain value ÷ Selling price × 100

Let Cost price = 100

Profit = 380

Selling price = 380 + 100 = 480

Increased cost price = 120

Percentage = 480−120480 × 100

⇒ 360480 × 100 = 75%
