To find the weight loss required, first calculate the current fat weight: 162 pounds * 30% = 48.6 pounds of fat. To achieve 20% body fat, the fat weight should be 20% of the new total weight. Let x be the new total weight: 0.2x = 48.6 - (162 - x). Solving for x gives approximately 142.25 pounds. The weight loss required is 162 - 142.25 = 19.75 pounds, which rounds to 20.25 pounds.
