Let \(x\) be the required score on test 3. The average performance across the three tests is calculated by dividing the sum of the scores by the total possible score, represented as \(\frac{40 + 54 + x}{600}\). To determine \(x\), solve the equation: \(\frac{40 + 54 + x}{600} = 0.3\). Solving yields \(x = 86\).
