20% of 8000 is 1600. There are different ways to calculate this, but one common method is to use the percent formula: (Whole × Percent)/100 = Part. In this case, the Whole is 8000 and the Percent is 20, so we get (8000 × 20)/100 = 1600. Another way to calculate this is to convert 20% to a decimal or fraction and then multiply it by 8000. For example, 20% as a decimal is 0.2, so 0.2 × 8000 = 1600. Therefore, 20% of 8000 is 1600.
