In the Hindu-Arabic system, we use the symbols 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. These symbols are called digits. Out of these ten digits, 0 is called an insignificant digit whereas the others are called significant digits 1. Natural Numbers Natural numbers are counting numbers. They are denoted by N. For Example N = {1,2,3,...}. * All natural numbers are positive. * Zero is not a natural number. Therefore, 1 is the smallest natural number. 2. Whole Numbers All natural numbers and zero form the set of whole numbers. Whole numbers are denoted by W. For Example W = {0,1,2,3,...} * Zero is the smallest whole number. * Whole numbers are also called as non-negative integers. 3. Integers Whole numbers and negative numbers form the set of integers. They are denoted by I. For Example I = {...,-4,-3,-2,-1,0,1,2,3,4,...} Integers are of two types. (i) Positive Integers - Natural numbers are called as positive integers. They are denoted by I+. For Example I+ = {1,2,3,4,...} For Free Study Material & Quizzes visit : www.mathsbyarunsir.com For any queries or suggestions email us:-Support@mathsbyarunsir.com or whatsapp @ 8881331466 7 @Crossword2022 (ii) Negative Integers - Negative of natural numbers are called as negative integers. They are denoted by I Best DI Questions for Competitive Exam by Arun sir For Example I- = {-1,-2,-3,-4,...} Note: '0' is neither +ve nor -ve integer. 4. Even Numbers A counting number which is divisible by 2, is called an even number. For Example 2, 4, 6, 8, 10, 12,...etc * The unit's place of every even number will be 0, 2, 4, 6 or 8. 5. Odd Numbers A counting number, which is not divisible by 2, is known as an odd number. For Example 1, 3, 5, 7, 9, 11, 13, 15, 17, 19,...etc. 6. Prime Numbers A counting numbers is called a prime number when it is exactly divisible by, 1 and itself. For Example 2, 3, 5, 7, 11, 13, ...etc. 2 is the only even number which is prime. A prime number is always greater than 1. 1 is not a prime number. Therefore, the lowest odd prime number is 3. * Every prime number greater than 3 can be represented by 6n + 1, where n is integer. 1 is neither prime nor composite, 2 is the only even number, that is prime. There are a total of 25 prime numbers up to 100 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97. * * * 7. * * 8. Composite Numbers Composite numbers are non-prime natural numbers. They must have at least one factor apart from 1 and itself. For Example, 4, 6, 8, 9, etc. Composite numbers can be both odd and even. 1 is neither a prime number nor composite number. * Co-primes Two natural numbers are said to be co-primes, if their HCF is 1. For Example (7, 9),(15, 16) Co-prime numbers may or may not be prime 9. Rational Numbers A number that can be expressed as p/q is called a rational number, where p and q are integers and q For Example , 3/5, 7/9, 8/9, 13/15 etc. 0. 10. Irrational Numbers The numbers that cannot be expressed in the form of p/q are called irrational numbers, where p and q are integers and q 0.

Best DI Questions for Competitive Exam by Arun sir Non-periodic infinite decimal fractions are called as irrational number 11. Perfect Square Number The numbers which is square of any number. e.g., -1,4,9,16,25 12. Perfect Numbers: The number, which is equal to the sum of Prime numbers, eg-6 = (3,2,1) ( 6 = 3 + 2 + 1) Formulas of Sum of Number Series 1. 1 + 2 + 3 + 4 + 5 + … + n = n(n + 1)/2 2. (12 + 22 + 32 + ..... + n2) = n ( n + 1 ) (2n + 1) / 6 3. (13 + 23 + 33 + ..... + n3) = (n(n + 1)/ 2)2 4. Sum of first n odd numbers = n2 5. Sum of first n even numbers = n (n + 1) Mathematical Formulas 1. (a + b)(a - b) = (a2 - b2) 2. (a + b)2 = (a2 + b2 + 2ab) 3. (a - b)2 = (a2 + b2 - 2ab) 4. (a + b + c)2 = a2 + b2 + c2 + 2(ab + bc + ca) 5. (a3 + b3) = (a + b)(a2 - ab + b2) 6. (a3 - b3) = (a - b)(a2 + ab + b2) 7. (a3 + b3 + c3 - 3abc) = (a + b + c)(a2 + b2 + c2 - ab - bc – ac) If (a + b + c) = 0 then a3 + b3 + c3 = 3abc Divisibility Rules A number is divisible by 2, if its unit's digit is any of 0, 2, 4, 6, 8. A number is divisible by 3, if the sum of its digits is divisible by 3. A number is divisible by 4, if the number formed by the last two digits is divisible by 4. A number is divisible by 5, if its unit's digit is either 0 or 5. A number is divisible by 6, if it is divisible by both 2 and 3. A number is divisible by 8, if the number formed by the last three digits of the given number is divisible by 8. A number is divisible by 9, if the sum of its digits is divisible by 9. A number is divisible by 10, if it ends with 0. A number is divisible by 11, if the difference of the sum of its digits at odd places and the sum of its digits at even places, is either 0 or a number divisible by 11. A number is divisible by 12, if it is divisible by both 4 and 3. Divisibility by 13: Subtract the last two digits from four times the rest. The result must be divisible by 13 For Free Study Material & Quizzes visit : www.mathsbyarunsir.com For any queries or suggestions email us:-Support@mathsbyarunsir.com or whatsapp @ 8881331466 9 @Crossword2022 i.e = 923: 9 × 4 - 23 = 13. Best DI Questions for Competitive Exam by Arun sir Divisibility by 17: Subtract the last two digits from two times the rest. e.g. 4,675: 46 × 2 - 75 = 17. Divisibility by 19: Add twice the last digit to the rest. e.g. 437: 43 + 7 × 2 = 57. Divisibility by 23: Add 7 times the last digit to the rest. E.g., 3128: 312 + 8 × 7 = 368. 36 + 8 × 7 = 92. Divisibility by 29: Add 9 times the last two digits to the rest. 5510: 55 + 10 × 9 = 145 = 5 × 29 Arithmetic Progression: - ( AP) a, a+d, a+2d, a+3d, where a = first term, d = difference = (second term - first term) = (third term-second term) nth term = Tn = a + (n - 1) d n Sum of n term = Sn = [2a+(n-1)d] 2 Geometric Progression ( GP) :a, ar, ar2, ar3, where a = first term, second term third term r= = =...

Usually, 5 questions are asked from this topic. If prepared well, you can easily score 5 marks in this topic with the help of some short tricks. Let us discuss the important concepts of Quadratic Equation with important tricks and examples in this Chapter now First and foremost, Relation between X and Y is established only when the relationship is defined for all solutions. 1. LINEAR EQUATIONS: In linear equations, both X and Y have only one value. So relation can be established easily. 3X+4Y=18, 5x+7Y= 12 (3X+4Y= 18)× 5, (5X+7Y=12)× 3 15X+20Y=90……..(i) 15X+21Y=36……..(ii) subtracting equation (i) from equation (2) we get, Y = -54, X = 78 Hence, X > Y 2. SQUARES: In this, solutions have both negative and positive value. X2=400 and Y2=4900 X = ±20 and Y = ±70 +70 is greater than both -20 and +20, but -70 is less than both -20 and +20. So, the answer will be Cannot be determined. TRICK: Whenever both equations are given in the square form, our ANSWER will be 'Can’t be determined.' 3. SQUARES AND SQUARE ROOT CASE. X2=900 and Y = √1600 We know that square root always gives a positive value. So, Y will have ONLY +40 NOT -40. X = ±30 and Y = +40 +40 is greater than both +30 and -30. Hence Y > X. 4. Cubes Case. If X3=1728, Y3=512 then, X=12 and Y = 8 X is greater than Y, so relation is X > Y. If X3= -1728 and Y3= 512 then, X= -12 and Y = 8 For Free Study Material & Quizzes visit : www.mathsbyarunsir.com For any queries or suggestions email us:-Support@mathsbyarunsir.com or whatsapp @ 8881331466 340 @Crossword2022 X is less than Y, so relation is X < Y. Note: When X3 > Y3, relationship is X > Y and when X3 < Y3, relation is X < Y. TRICK: When both equations are in cube form. If X3 > Y3, then X > Y and X3 < Y3, then X < Y. 5. Square and cube cases. If X2=36 and Y3=216 then X = +6, -6 and Y=6 So, Y = 6 is equal to X = 6 and Y = 6 is greater than X = -6. So, Y ≥ X If X2=25 and Y3=64 then X = +5, -5 and Y = 4 So, Y = 4 is greater than X = -5 and less than X = +5, So relation Can’t be Determined. Table Method to solve Quadratic Equations Easily 1.
