A mobile phone is sold at a profit of 80%. The nominal profit is approximately what percentage of the selling price of the mobile phone?

33.33% 28.56% 44.44% 36.66%

44.44%

Let cost price = 100x Profit = 80% So, Selling price = 100x + 80x = 180x  Now, Profit with respect to selling price = \(\frac{180x - 100x}{180x}\) × 100 = 44.44%
