Concept: The Divisibility Rules help us to determine if a number will divide into another number without actually having to divide. Rules can be made for any of the number but here we will learn the most common ones. Here we talk about Divisibility Rules of Mathematics for numbers 3, 6, and 9 Prerequisite: Person should […]

Concept: Calculations of Square’s up to 50th number Prerequisite: Person should know squares till 25th number How: Suppose a number N whose square need to be taken. Now Square will be calculated in 2 parts as mentioned. First Part Second Part = (Given number – 25) ⇒ (N-25) (50 -Given number)² ⇒ (50 – N)² Special […]
Catch up the study material for Ratios & Proportions Here Examples of Ratios — Example 1: A sum of money is to be distributed among A, B, C, D in the proportion of 5:2:4:3. If A gets Rs. 1000 more than C, what is B’s share? Solution: Let the share A, B, C, D to be […]
In certain situations, comparison by division makes it better than doing comparison by taking the difference. The comparison by division is called the ratio. In this chapter we will introduce the concept of ratios & proportions. Ratios — […]
Trigonometry The word ‘Trigonometry’ means measurement of triangles. Concept of Perpendicular, Base and Hypotenuse in a Right Triangle For any acute angle θ in a right angled triangle; The side opposite to the acute angle is called the Perpendicular. The side adjacent to Perpendicular is called the Base. […]
〉〉 Without solving, comment upon the nature of the roots for following 3 Equations. Example 1: 6x² – 13x + 4 = 0 From ax² + bx + c=0; by comparing, we get a = 6, b = -13, c = 4; So coefficients are real. Discriminant ‘D’= b² – 4 a c ⇒ (-13)² […]
Equation: An equation is a mathematical sentence that uses the equal sign (=) to show that two expressions are equal. Example 1: 3+4=7 ; Example 2: 3a+4b=1
