3 Ways to Understand Maximizing and Minimizing in Hard TPA Questions1. IntroductionIn several TPA questions, we are asked to find values such that a certain entity is maximized or minimized. The manner in which you approach such questions varies from the question to question. In this article, we will showcase three different ways to answer such questions.
2. TPA_010 Rashika is beginning a
In this question, maximization and minimization is done through visualizing the Venn Diagram.
Watch the solution at 5:25 to understand how we did the optimization through visualization.
3. TPA_081 Lee is planning a tripThis is a fairly complex question in which we need to find the range of the average speed and then we need to find the values such that this range is minimized.
So to solve this question, first we need to use the information about rounding to find the range of distance and time, separately.
Then we calculate the range of average speed. And to do this we use our understanding of how a fraction is maximized and how it is minimized.
And then lastly, we take these decimal values and use the information in the answer choices to minimize y – x.
In order to ensure that you understand every bit of this processing,
watch the video solution from 1:22 onwards.
4. TPA_071 A farmer wants to allocateThis is a very interesting maximizing and minimizing question pertaining to the product of 5 numbers for which we need to change one number such that the product is maximized and likewise change one number such that product is minimized.
Watch the solution at 6:11 to see how to approach this question.
5. SummaryIn this article, we saw three difficult official questions in which the minimization and maximization happened in three different ways:
- By visualizing the venn diagram.
- By using the understanding of rounding and fractions.
- By using our understanding of product.
Ensure that you understand all these techniques. As you build these skills, you will see your accuracy in TPA questions improve.
