GMAT Solution Setup: Balance Scale (A Shortcut for Weighted Averages)

The balance scale shortcut is a fast way to solve many weighted average and mixture problems on the GMAT without setting up equations. Think of a weighted average like a balance scale: larger quantities pull the average closer to their value. Because of this relationship, the ratio of the quantities equals the inverse (flipped) ratio of the distances from the average. Recognizing this relationship can save significant time on GMAT Quant and Data Insights problems involving weighted averages and mixtures. The example used in this video: The cost of a mixture that contains candy-coated chocolate pieces and salted pieces in the ratio... This way of thinking is part of the broader GMAT approach I teach in my book, which focuses on clarity, decision-making, and avoiding common thinking traps on test day.
