Mensuration में Percentage वाले सवाल | Most Repeated Questions | Maths by Rishi Sir
Welcome to another insightful session with Rishi Sir! In today's video, we delve deep into one of the most crucial and often asked topics in mathematics - Mensuration with a focus on percentage-based questions. If you are preparing for competitive exams like SSC, Railway, Banking, or any other exams where mathematics plays a significant role, this video is tailor-made for you. Whether you're a beginner trying to build a solid foundation or someone who’s looking to revise and master the concepts, this video has something for everyone.
What is Mensuration?
Mensuration is a branch of mathematics that deals with the measurement of geometric figures, such as areas, volumes, and surface areas of different shapes. It is an essential topic in both academic and competitive exams. Often, the questions in exams combine concepts of mensuration with other mathematical principles like percentages, ratios, and algebra to create more complex and analytical questions.
In this video, Rishi Sir will guide you through such problems where percentages are used in conjunction with mensuration formulas. We will cover questions that have been most frequently asked in exams, making sure you are well-prepared for any challenge that comes your way.
Why Focus on Percentage-Based Mensuration Questions?
In competitive exams, questions are not always straightforward. Examiners often test students' ability to combine multiple concepts. One of the most common combinations is between percentages and mensuration. For example, you might be asked to calculate how much an area or volume changes when the dimensions of a shape are increased or decreased by a certain percentage. These questions not only test your understanding of mensuration formulas but also your ability to handle percentage calculations efficiently.
This is why mastering percentage-based questions is crucial. If you can solve these questions with confidence, you’ll not only save time in exams but also secure those extra marks that could make all the difference in your ranking.
What Will You Learn in This Video?
In this session, Rishi Sir will cover the following:
Basic Concepts of Mensuration: We will begin with a quick revision of essential mensuration formulas for 2D and 3D shapes like squares, rectangles, circles, cylinders, cones, and spheres. Having a strong grasp of these formulas is the key to solving more complex problems later on.
Understanding Percentages in Mensuration: The concept of percentages will be introduced within the realm of mensuration. You will learn how to apply percentage increases or decreases to the dimensions of geometric figures and how these changes affect the overall area, surface area, or volume of the figure.
Most Repeated Exam Questions: Rishi Sir has carefully selected a range of questions that are frequently asked in various competitive exams. These questions are designed to test your understanding of both mensuration and percentages. By working through these problems, you’ll gain insight into the kind of challenges examiners present and how to approach them efficiently.
Step-by-Step Problem Solving: Rishi Sir breaks down each question into easy-to-follow steps. First, you’ll identify the relevant mensuration formula, then apply percentage changes, and finally calculate the required values. This approach ensures that you build a systematic method of solving these types of questions in exams.
Tips and Tricks: In addition to detailed explanations, Rishi Sir will share valuable tips and shortcuts to solve these questions faster. Time management is crucial in competitive exams, and knowing these shortcuts will give you an edge over other candidates.
