PORCENTAGEM: A pegadinha de aumento e desconto que engana 95% dos candidatos! 😱📈

Does your intuition usually save you or trip you up when solving successive percentage problems? 🧠✨ Our Question 18 presents an absolute classic of exam board traps: a product undergoes a 25% increase and then immediately receives a 20% discount on the new price. At first glance, most people do the direct mental calculation: and confidently mark that the product became "more expensive" (Option A). But that's exactly where the danger lies! In financial mathematics, when we change the value of the product, the basis for calculating the discount also changes completely. The 20% discount is not applied to the original value from the beginning, but to the value that was already inflated! In this video, I, @prof.franciscodeassis, will teach you the famous "100% Trick". You'll see how simulating a fictitious initial price of R$100.00 transforms a seemingly complex issue into a simple and visual calculation, leading you straight to the correct answer without any room for error! 🎯 What you will learn in this lesson: Successive Percentage Variation: Understand once and for all why increases and discounts with the same values ​​do not cancel each other out and how the calculation base changes everything. The 100 Trick: The most practical technique in the world for solving commercial percentage problems without needing to load variables or long equations. Logical-Financial Reasoning: How to critically analyze alternatives to eliminate obvious distractors created by the examining board.
