## FAQs on RD Sharma Class 11 Solutions Chapter 31 - Mathematical Reasoning (Ex 31.1) Exercise 31.1

**1. How to do Mathematical Reasoning in an easy way?**

RD Sharma Class 11 Solutions is one such book that provides solutions to all chapters including Chapter 31 Mathematical Reasoning. This type of reasoning helps students to solve problems which have more than one answer or where there can be multiple solutions. There is no difference between all kinds of reasoning but mathematical reasoning covers more topics than classifications like it also includes linear programming problems where we need to find out minimum cost or maximum profit etc.

**2. What are the topics covered in this chapter?**

This chapter starts with an introduction to Logic Gates followed by Truth Tables and Boolean Algebra. In the next section, Applications of Boolean Algebra are covered which includes Karnaugh Maps, Designing Digital Circuits using ICs, etc. The next type of reasoning is called classification where students learn how to group objects based on their characteristics like size or shape or colour or any other feature. Here are some examples: classify animals according to their habitat (land/water), group fruits depending on their colour, classify numbers according to their divisibility by a particular number, classify students according to the city they come from.

**3. What are the different types of questions asked in the Mathematical Reasoning question paper for RD Sharma Class 11 Solutions Chapter 31 ?**

In this type of reasoning, various topics covered include classifications, linear programming, etc., and some examples for each topic mentioned above includes classification- Group animals according to their habitat (land/water), group fruits depending on their colour, classify numbers according to their divisibility by a particular number. Linear Programming- Minimise cost given maximum profit; maximise profit given minimum cost. Students should make sure they understand all the concepts before attempting any question. Practice as many questions as possible and check your answers with the solutions provided in the book. This will help you score better marks in your examination.
