Matemática Financeira para Concursos:Aplicou R$ 2.400 a 2% ao mês: Qual é o MONTANTE final?

Do you know the difference between calculating the interest earned on an investment and finding the final amount? 🧠✨ Our Question 20 presents the classic Simple Interest problem from public service exams: a candidate invested R$ 2,400.00 at a rate of 2% per month for 5 months. The examiners love to test your attention! If you use the formula J=C.I.T (or do the calculation in your head) and find R$ 240.00 in interest, you'll look at the options and rush to mark Letter A (R$ 2,520.00) in a moment of distraction, adding incorrectly or confusing the values. 🎯 What you will learn in this lesson: Quick Percentage Calculation: How to use the "cut the zeros" technique, without struggling with fractions. The Simple Interest Rule: How to multiply the monthly return by the total investment time (5 months) directly. The Secret of the Amount: The definitive warning to never forget the formula M = C + J (Amount = Capital + Interest) before marking your option. Grab your paper and pen, pause the video and do the calculation! Then follow along with the solution to see if you escaped the trap set by the exam board! 📢 JOIN OUR STUDY COMMUNITY: 👍 Did you like the trick to avoid mistakes in the amount calculation?
