In our daily life, we come across various type of data, for example, teachers collect the marks of all students in the class. They will arrange it in table for easy calculations and interpretations. Teachers will be able to calculate the highest and lowest score in the class, most frequently occurring score (mode), arithmetic mean of the marks, etc. In this chapter, we will study arithmetic mean, median and mode of collected data, representation of data using bar graph and definition of probability.
CBSE NCERT solutions for class 7 maths chapter 4 Simple Equations: In this chapter, there are a total of 4 exercises and the solutions to all are provided. This lesson is all about what an equation is, how to solve simple equations and how can we use equations in our daily life. In NCERT solutions for class 7 maths, you will study the solutions of some real-life problems using a simple equation. This is a very important chapter for the upcoming higher classes also.
Solutions of NCERT class 7 maths chapter 5 Lines and Angles: This is one of the basic chapters of geometry and you should give special attention to this chapter because understanding geometry in higher classes will be dependent on how well you understand this lesson. The chapter introduces the concepts of lines and angles. These NCERT solutions for class 7 maths are also for parallel lines, what are intersections of lines and the different types of angles such as complementary angles, alternate angles, etc. The chapter has only 2 exercises and all the solutions to the exercises can be downloaded by clicking the above link.
NCERT solutions for class 7 maths chapter 6 The Triangle and its Properties: Here you will have 5 exercises with detailed solutions to each and every question. This chapter is also an important part of geometry. You will study different types of triangles - equilateral, right-angled and isosceles. The properties of triangles will also be taught. At the end of the chapter, an important concept known as Pythagoras theorem will be taught. This has relevance even in class 8, 9 and 10 and further too.
CBSE NCERT solutions for class 7 maths chapter 7 Congruence of Triangles: This is another chapter about triangles which deals with congruency of two triangles. Two figures are said to be congruent if they have the same size and shape. We will study the congruent triangle and what are the different criteria used to check if a given triangle is congruent or not congruent.

There are 3 exercises to solve in this chapter. You can download all the free solutions for these exercises and learn better with their help.
NCERT solutions for class 7 maths chapter 9 Rational Numbers: After learning about Integers in chapter 1 you will get to know another type of numbers in chapter 9 which are rational numbers. So what are rational numbers? A number in the form of p/q where p and q are integers and q is not zero can be termed as rational. Every integer can be expressed as a rational number. Every fraction is a rational number but every rational number need not be a fraction since fractions contain only positive integers. We will study the concept of rational numbers and operations on rational numbers in this chapter. The chapter has 2 exercises and you will find all the NCERT solutions here.
CBSE NCERT solutions for class 7 maths chapter 10 Practical Geometry: Here, you will learn about certain basic constructions using a ruler, compass, and protractor. The construction of the parallel line to a given line at some point outside the line and construction of triangles using the concept of congruent triangles will be taught. Construction of triangle using SAS, ASA, SSS and RHS criteria of congruence will also be taught in this leasson.
Solutions of NCERT class 7 maths chapter 11 Perimeter and Area: You will study about perimeter and area of the rectangle, triangle, and parallelogram here. If we have to calculate how much sheet is required to cover a roof in the shape of a parallelogram we have to calculate the area of the roof. If you want to frame a picture in the shape of a triangle then you have to calculate the perimeter of the triangle to know how much length of the frame is required. There are many real-life problems mentioned in the chapter for which solutions have also been given.
