In this section, we will take up the Average (Basics and Based on Number System) topic and deal with all the concepts and formulae in it. Average: An average of the given data is the sum of all the observations in it divided by number of observations. Average is also called the Arithmetic Mean.
In this section, we will take up the Quadratic Equations part and deal with all the concepts and formulae in it. We will also see some Cubic Equations formulae and solve few problems on them Quadratic Equations are equations of degree 2 i.e. the power of at least one variable must be 2 and also the maximum power on any
In this section, we will discuss the Linear Equation. Linear Equation part of our syllabus is comparatively easy and has very few concepts. What is an Equation? An equation is a statement that denotes two different mathematical expressions as equal. It consists of ‘=’ sign between two mathematical expressions. It is generally used in algebra and is
In this section, we will begin with the Time and Work topic of your exams. The concept of Time and Work is moreover based on Unitary Method and LCM. Before we begin, we should know some basic relations: Time(T) ∝ Work(W) i.e. To do more work we will need more time and vice versa. Time(T) ∝ 1/Person(P) i.e. More person will do the same work in
In this section, we will continue the Simple and Compound Interest topic. Today we will discuss some questions which involve the Concepts of both SI and CI (SI – CI Mix) and see some problems which come in Exam under this topic. SI – CI Mix: There are certain problems which involve concepts of both
In this section, we will study the Ratio and Proportion topic [RATIO] Ratio is used to show comparison between two similar quantities. For example, Suppose Aman bought 4 apples and 5 mangos then the ratio of Apple: Mango= 4:5 (read as 4 is to 5 or 4 ratio 5). Here we have compared number of items (similar quantity).
Working to bring significant changes in online-based learning by doing extensive research for course curriculum preparation, student engagements, and looking forward to the flexible education!
